CVE-2026-64230 1 Linux 1 Linux Kernel 2026-07-26 N/A
In the Linux kernel, the following vulnerability has been resolved: regulator: tps65219: fix irq_data.rdev not being assigned Commit 64a6b577490c ("regulator: tps65219: Remove debugging helper function") removed the tps65219_get_rdev_by_name() helper along with the irq_data.rdev assignment that depended on it. This left irq_data.rdev uninitialized for all IRQs, causing undefined behavior when regulator_notifier_call_chain() is called from the IRQ handler: Internal error: Oops: 0000000096000004 pc : regulator_notifier_call_chain lr : tps65219_regulator_irq_handler Call trace: regulator_notifier_call_chain tps65219_regulator_irq_handler handle_nested_irq regmap_irq_thread irq_thread_fn irq_thread kthread ret_from_fork Instead of restoring a dedicated lookup array, restructure the probe function to combine regulator registration with IRQ registration in the same loop. This way the rdev returned by devm_regulator_register() is naturally available for assigning to irq_data.rdev without any auxiliary data structure. Non-regulator IRQs (SENSOR, TIMEOUT) that don't correspond to any registered regulator are registered with rdev=NULL, and the IRQ handler is protected with a NULL check to avoid crashing.
CVE-2026-64234 1 Linux 1 Linux Kernel 2026-07-26 N/A
In the Linux kernel, the following vulnerability has been resolved: tty: serial: pch_uart: add check for dma_alloc_coherent() Add a check for dma_alloc_coherent() failure to prevent a potential NULL pointer dereference in dma_handle_rx(). Properly release DMA channels and the PCI device reference using a goto ladder if the allocation fails.
CVE-2026-64236 1 Linux 1 Linux Kernel 2026-07-26 N/A
In the Linux kernel, the following vulnerability has been resolved: i2c: davinci: fix division by zero on missing clock-frequency When the 'clock-frequency' property is missing from the device tree, the driver falls back to DAVINCI_I2C_DEFAULT_BUS_FREQ. However, this macro was defined in kHz (100), whereas the device tree property is expected in Hz. The probe function divided the fallback value by 1000, causing integer truncation that resulted in dev->bus_freq = 0. This triggered a deterministic division-by-zero kernel panic when calculating clock dividers later in the probe sequence. Fix this by redefining DAVINCI_I2C_DEFAULT_BUS_FREQ in Hz (100000) to match the expected device tree property unit, allowing the existing division logic to work correctly for both cases.
CVE-2026-64244 1 Linux 1 Linux Kernel 2026-07-26 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: drivers/base/memory: set mem->altmap after successful device registration If __add_memory_block() fails at xa_store() (under memory pressure for example), device_unregister() is called, which eventually triggers memory_block_release() with mem->altmap still set, causing a WARN_ON(mem->altmap). This was triggered by modifying virtio-mem driver. Fix this by delaying the assignment of mem->altmap until after __add_memory_block() has succeeded.
CVE-2026-64250 1 Linux 1 Linux Kernel 2026-07-26 N/A
In the Linux kernel, the following vulnerability has been resolved: LoongArch: Report dying CPU to RCU in stop_this_cpu() This is a port of MIPS commit 9f3f3bdc6d9dac1 ("MIPS: smp: report dying CPU to RCU in stop_this_cpu()"). smp_send_stop() parks all secondary CPUs in stop_this_cpu(). And the function marks the CPU offline for the scheduler via set_cpu_online(false) but never informs RCU, so RCU keeps expecting a quiescent state from CPUs that are now spinning forever with interrupts disabled. As long as nothing waits for an RCU grace period after smp_send_stop() this is harmless, which is why it went unnoticed. However, since commit 91840be8f710370 ("irq_work: Fix use-after-free in irq_work_single() on PREEMPT_RT"), irq_work_sync() calls synchronize_rcu() on architectures without an irq_work self-IPI, i.e. where arch_irq_work_has_interrupt() returns false. Any irq_work_sync() issued in the reboot/shutdown/halt path after smp_send_stop() then blocks on a grace period that can never complete, hanging the reboot: WARNING: CPU: 0 PID: 15 at kernel/irq_work.c:144 irq_work_queue_on ... rcu: INFO: rcu_sched detected stalls on CPUs/tasks: rcu: Offline CPU 1 blocking current GP. rcu: Offline CPU 2 blocking current GP. rcu: Offline CPU 3 blocking current GP. This issue needs some hacks to reproduce, and it was not noticed on LoongArch because arch_irq_work_has_interrupt() usually returns true. Call rcutree_report_cpu_dead() once interrupts are disabled, mirroring the generic CPU-hotplug offline path, so RCU stops waiting on the parked CPUs and grace periods can still complete. LoongArch shuts down all CPUs here without going through the CPU-hotplug mechanism, so this report is not otherwise issued.
CVE-2026-64253 1 Linux 1 Linux Kernel 2026-07-26 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: kernel/fork: clear PF_BLOCK_TS in copy_process() PF_BLOCK_TS is only set in blk_time_get_ns() when current->plug is non-NULL, and blk_finish_plug() clears it via __blk_flush_plug() before NULLing the plug pointer. copy_process() breaks the invariant by inheriting PF_BLOCK_TS from the parent while resetting the child's plug to NULL. Clear PF_BLOCK_TS alongside that assignment so callers can rely on "PF_BLOCK_TS set implies current->plug != NULL" and dereference current->plug unguarded.
CVE-2026-64256 1 Linux 1 Linux Kernel 2026-07-26 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: xfs: don't wrap around quota ids in dqiterate LOLLM noticed that q_id is an unsigned 32-bit variable. If it happens to be set to XFS_DQ_ID_MAX due to a filesystem that actually has a dquot for ID_MAX, then this addition will truncate to zero and the iteration starts over. Fix this by casting to u64.
CVE-2026-64258 1 Linux 1 Linux Kernel 2026-07-26 N/A
In the Linux kernel, the following vulnerability has been resolved: fuse-uring: remove request-less entries from ent_w_req_queue to fix NULL deref If a copy into the userspace ring buffer fails, a request will be terminated and fuse_uring_req_end() will set ent->fuse_req to NULL but it will leave the entry on ent_w_req_queue in FRRS_FUSE_REQ state. This can lead to a NULL deref if the request expiration logic scans ent_w_req_queue in the window before the entry is moved off it. Fix this by taking the entry off ent_w_req_queue and changing its state from FRRS_FUSE_REQ to FRRS_INVALID before terminating the request.
CVE-2026-64278 1 Linux 1 Linux Kernel 2026-07-26 N/A
In the Linux kernel, the following vulnerability has been resolved: i2c: imx-lpi2c: mark I2C adapter when hardware is powered down On some i.MX platforms, certain I2C client drivers keep a periodic workqueue which continues to trigger I2C transfers. During system suspend/resume, there exists a time window between: - suspend_noirq and the system entering suspend - the system starting to resume and resume_noirq In this window, the I2C controller resources such as clock and pinctrl may already be disabled or not yet restored. If a workqueue triggers an I2C transfer in this period, the driver attempts to access I2C registers while the hardware resources are unavailable, which may lead to system hang. Mark the I2C adapter as suspended during noirq suspend and block new transfers until resume, ensuring that I2C transfers are only issued when hardware resources are available.
CVE-2026-64282 1 Linux 1 Linux Kernel 2026-07-26 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Don't leak PFN when kvm_translate_vncr() races MMU notifier In the case that kvm_translate_vncr() races with an MMU notifier the early return does not release a reference on the faulted in PFN. Add the necessary call to kvm_release_faultin_page() for the unused PFN.
CVE-2026-64290 1 Linux 1 Linux Kernel 2026-07-26 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: iommufd: Break the loop on failure in iommufd_fault_fops_read() On a copy_to_user() failure inside the inner list_for_each_entry, only the inner loop breaks; the outer while re-fetches the just-restored fault group and retries the failing copy_to_user() forever, spinning the reader at 100% CPU with fault->mutex held. Check rc after the inner loop and break the outer while as well.
CVE-2026-64305 1 Linux 1 Linux Kernel 2026-07-26 7.0 High
In the Linux kernel, the following vulnerability has been resolved: crypto: qat - protect service table iterations with service_lock The service_table list is protected by service_lock when entries are added or removed (in adf_service_add() and adf_service_remove()), but several functions iterate over the list without holding this lock. A concurrent adf_service_register() or adf_service_unregister() call could modify the list during traversal, leading to list corruption or a use-after-free. Fix this by holding service_lock across all list_for_each_entry() iterations of service_table in adf_dev_init(), adf_dev_start(), adf_dev_stop(), adf_dev_shutdown(), adf_dev_restarting_notify(), adf_dev_restarted_notify(), and adf_error_notifier(). The lock ordering is safe: callers of the static helpers (adf_dev_up() and adf_dev_down()) acquire state_lock before service_lock, and no event_hld callback or service_lock holder ever acquires state_lock in the reverse order.
CVE-2026-64307 1 Linux 1 Linux Kernel 2026-07-26 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: crypto: ccp - Do not initialize SNP for ioctl(SNP_CONFIG) Sashiko notes: > if SEV initialization fails and KVM is actively running normal VMs, could a > userspace process trigger this code path via /dev/sev ioctls (e.g., > SEV_PDH_GEN) and zero out MSR_VM_HSAVE_PA globally? Would the next VMRUN > execution for an active VM trigger a general protection fault and crash the > host? Refuse to re-try initialization if SNP is not already initialized for SNP_CONFIG. This is technically an ABI break: before if SNP initialization failed it could be transparently retriggered by this ioctl, and if no VMs were running, everything worked fine. Hopefully this is enough of a corner case that nobody will notice, but someone does, there are a few options: * do something like symbol_get() for kvm and refuse to initialize if KVM is loaded * check each cpu's HSAVE_PA for non-zero data before re-initializing * once initialization has failed, continue to refuse to initialize until the ccp module is unloaded
CVE-2026-64309 1 Linux 1 Linux Kernel 2026-07-26 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: crypto: ccp - Do not initialize SNP for ioctl(SNP_COMMIT) Sashiko notes: > if SEV initialization fails and KVM is actively running normal VMs, could a > userspace process trigger this code path via /dev/sev ioctls (e.g., > SEV_PDH_GEN) and zero out MSR_VM_HSAVE_PA globally? Would the next VMRUN > execution for an active VM trigger a general protection fault and crash the > host? The SNP_COMMIT command does not require the firmware to be in any particular state. Skip initializing it if it was previously uninitialized. The SEV-SNP firmware specification doc 56860 does not mention SNP_COMMIT in Table 5 as a command that is allowed in the UNINIT state, but it is in fact allowed and a future documentation update will reflect that.
CVE-2026-64316 1 Linux 1 Linux Kernel 2026-07-26 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: crypto: caam - use print_hex_dump_devel to guard key hex dumps Use print_hex_dump_devel() for dumping sensitive key material in *_setkey() and gen_split_key() to avoid leaking secrets at runtime when CONFIG_DYNAMIC_DEBUG is enabled.
CVE-2026-64321 1 Linux 1 Linux Kernel 2026-07-26 7.0 High
In the Linux kernel, the following vulnerability has been resolved: nvme: target: rdma: fix ndev refcount leak on queue connect nvmet_rdma_queue_connect() calls nvmet_rdma_find_get_device() which acquires a reference on the returned ndev via kref_get(). On the path where the host queue backlog is exceeded and the function returns NVME_SC_CONNECT_CTRL_BUSY, reference of ndev is not released, leaking the kref. Fix this by adding a goto to the existing put_device label before the early return.
CVE-2026-64325 1 Linux 1 Linux Kernel 2026-07-26 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7921/mt7925: fix NULL dereference in CSA beacon This patch is based on a BUG as reported by Bongani Hlope at https://lore.kernel.org/all/20260502125824.425d7159@bongani-mini.home.org.za/ When a channel-switch announcement (CSA) beacon is received, cfg80211 queues a wiphy work item that eventually calls mt7921_channel_switch_rx_beacon(). If the station disconnects (or the channel context is otherwise torn down) between the time the work is queued and the time it runs, the driver's dev->new_ctx pointer can already have been cleared to NULL. mt7921_channel_switch_rx_beacon() then dereferences new_ctx unconditionally, triggering a NULL pointer dereference at address 0x0: BUG: kernel NULL pointer dereference, address: 0000000000000000 RIP: 0010:mt7921_channel_switch_rx_beacon+0x1f/0x100 [mt7921_common] The same missing guard exists in mt7925_channel_switch_rx_beacon(), which shares the same code pattern introduced by the same commit. Add an early-return NULL check for dev->new_ctx in both mt7921_channel_switch_rx_beacon() and mt7925_channel_switch_rx_beacon(). When new_ctx is NULL there is no pending channel switch to process, so returning immediately is the correct and safe action.

CVE-2026-64341 1 Linux 1 Linux Kernel 2026-07-26 7.0 High
In the Linux kernel, the following vulnerability has been resolved: USB: iowarrior: fix use-after-free on disconnect race mutex_unlock() may access the mutex structure after releasing the lock and therefore cannot be used to manage lifetime of objects directly (unlike spinlocks and refcounts). [1][2] Use a kref to release the driver data to avoid use-after-free in mutex_unlock() when release() races with disconnect(). [1] a51749ab34d9 ("locking/mutex: Document that mutex_unlock() is non-atomic") [2] 2b9d9e0a9ba0 ("locking/mutex: Clarify that mutex_unlock(), and most other sleeping locks, can still use the lock object after it's unlocked")
CVE-2026-64480 1 Linux 1 Linux Kernel 2026-07-26 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: ALSA: ice1712: check snd_ctl_new1() return value snd_ctl_new1() can return NULL when memory allocation fails. The ice1712 driver calls snd_ctl_new1() without checking the return value before dereferencing the pointer in multiple places (ice1712.c, ice1724.c, aureon.c), which can lead to NULL pointer dereferences. Add NULL checks after snd_ctl_new1() calls and return -ENOMEM if any fails.
CVE-2026-64528 1 Linux 1 Linux Kernel 2026-07-26 N/A
In the Linux kernel, the following vulnerability has been resolved: tty: serial: samsung: Remove redundant port lock acquisition in rx helpers Sashiko identified a deadlock when the console flow is engaged [1]. When console flow control is enabled (UPF_CONS_FLOW), s3c24xx_serial_stop_tx() calls s3c24xx_serial_rx_enable() and s3c24xx_serial_start_tx() calls s3c24xx_serial_rx_disable(). The serial core framework invokes the .stop_tx() and .start_tx() callbacks with the port->lock spinlock already held. Furthermore, all internal driver paths that invoke stop_tx (such as the DMA TX completion handler s3c24xx_serial_tx_dma_complete() or the PIO TX IRQ handler s3c24xx_serial_tx_irq()) also acquire port->lock prior to calling it. (Note that s3c24xx_serial_start_tx() is only invoked by the serial core). However, s3c24xx_serial_rx_enable() and s3c24xx_serial_rx_disable() unconditionally attempt to acquire port->lock again using uart_port_lock_irqsave(). Since spinlocks are not recursive, this causes a deadlock on the same CPU when console flow control is engaged. Remove the redundant lock acquisition from both rx helper functions.
