| Netty is an asynchronous, event-driven network application framework. Prior to 4.1.136.Final and 4.2.16.Final, io.netty.handler.codec.dns.AbstractDnsRecord, io.netty.handler.codec.dns.DefaultDnsRecordDecoder.decodeRecord(), and io.netty.handler.codec.dns.DnsCodecUtil.decompressDomainName() failed to release retained or newly allocated ByteBuf objects when IDN.toASCII() or encodeDomainName() rejected a malformed domain name, allowing unauthenticated remote DNS packets to leak direct memory incrementally until denial of service. This issue is fixed in versions 4.1.136.Final and 4.2.16.Final. |
| Klever-Go is the Go implementation of the Klever blockchain protocol. In versions prior to 1.7.18, the account-data trie syncers are vulnerable to a resource-exhaustion flaw that leaks bounded throttler slots on error paths. In syncDataTrie() (in both userAccountsSyncer.go and kappAccountsSyncer.go), StartProcessing() reserves a slot from the NumGoRoutinesThrottler, but the corresponding EndProcessing() is only called on the success path and on the duplicate-root early return. As a result, any error from trie.NewTrie(), trie.NewTrieSyncer(), or trieSyncer.StartSyncing() (including the network-dependent timeout path) permanently consumes one slot for the lifetime of the throttler. An attacker who can repeatedly cause trie-node sync failures or timeouts during bootstrap can exhaust the bounded throttler, after which further account-data trie syncs stop making progress and SyncAccounts() returns a timeout. Because epoch bootstrap in syncUserAccountsState() and syncKappAccountsState() aborts on any such error, this causes bootstrap to fail, a core availability issue affecting fresh, restarting, or resyncing nodes and validators. This issue is fixed in version 1.7.18. |
| In the Linux kernel, the following vulnerability has been resolved:
gpio: rockchip: teardown bugs and resource leaks
Address several teardown issues and resource leaks in the driver's remove
path and error handling:
1. Debounce clock reference leak: The debounce clock (bank->db_clk) is
obtained using of_clk_get() which increments the clock's reference
count, but clk_put() is never called. Register a devm action to
cleanly release it on unbind. Note that of_clk_get(..., 1) remains
necessary over devm_clk_get() because the DT binding does not define
clock-names, precluding name-based lookup.
2. Unregistered chained IRQ handler: The chained IRQ handler is not
disconnected in remove(). If a stray interrupt fires after the driver
is removed, the kernel attempts to execute a stale handler, leading
to a panic. Fix this by clearing the handler in remove().
3. IRQ domain leak: The linear IRQ domain and its generic chips are
allocated manually during probe but never removed. Remove the IRQ
domain during driver teardown to free the associated generic chips
and mappings.

| HttpClient based on the classic i/o model fails to correctly release the underlying connection back to the connection manager if it encounters an invalid or unsupported `Content-Encoding` header value in the response message. Please note this defect does not affect HttpClient based on the async i/o model.
This issue affects Apache HttpComponents Client: from 5.0-alpha1 through 5.6.2. |
| In the Linux kernel, the following vulnerability has been resolved:
svcrdma: wake sq waiters when the transport closes
Threads parked in svc_rdma_sq_wait() on sc_sq_ticket_wait or
sc_send_wait can hang indefinitely in TASK_UNINTERRUPTIBLE state
across transport teardown, pinning svc_xprt references and
blocking svc_rdma_free().
The close path sets XPT_CLOSE before invoking xpo_detach and both
wait_event predicates include an XPT_CLOSE term, but the
predicates are re-evaluated only on wakeup. sc_sq_ticket_wait has
no completion-driven wake path; it is advanced solely by the
chained ticket handoff inside svc_rdma_sq_wait() itself. Without
an explicit wake at close, parked threads never observe
XPT_CLOSE, hold their svc_xprt_get reference forever, and
svc_rdma_free() blocks on xpt_ref dropping to zero.
Two close entry points reach this transport. Local teardown runs
svc_rdma_detach() from svc_handle_xprt() -> svc_delete_xprt() ->
xpo_detach() on a worker thread. A remote disconnect arrives at
svc_rdma_cma_handler(), which calls svc_xprt_deferred_close():
that sets XPT_CLOSE and enqueues the transport but does not
access either RDMA waitqueue, so a worker already parked in
svc_rdma_sq_wait() never re-evaluates its predicate. With every
worker parked on this transport, no thread is available to run
the local teardown either, and the wake site there is
unreachable.
Introduce svc_rdma_xprt_deferred_close(), a thin svcrdma wrapper
that calls svc_xprt_deferred_close() and then wakes both
sc_sq_ticket_wait and sc_send_wait. Convert the svcrdma producers
that called svc_xprt_deferred_close() directly:
svc_rdma_cma_handler(), qp_event_handler(),
svc_rdma_post_send_err(), svc_rdma_wc_send(), the sendto drop
path, the rw completion error paths, and the recvfrom flush and
read-list error paths.
Wake both waitqueues from svc_rdma_detach() as well. The
synchronous svc_xprt_close() path (backchannel ENOTCONN, device
removal via svc_rdma_xprt_done) reaches detach without flowing
through svc_xprt_deferred_close() and therefore does not invoke
the new helper.
[ cel: add svc_rdma_xprt_deferred_close() to complete the fix ] |
| 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. |
| In the Linux kernel, the following vulnerability has been resolved:
net: ti: icssm-prueth: fix eth_ports_node leak in probe
The error path on of_property_read_u32() failure inside
icssm_prueth_probe() returns without putting eth_ports_node,
which was acquired before the for_each_child_of_node() loop.
Drop it before returning. |
| In the Linux kernel, the following vulnerability has been resolved:
i2c: tegra: fix pm_runtime leak on mutex_lock failure
If tegra_i2c_mutex_lock() fails, the function returns without calling
pm_runtime_put(), leaking the runtime PM reference acquired by the
preceding pm_runtime_get_sync(). This prevents the device from ever
entering runtime suspend.
Add the missing pm_runtime_put() before returning on lock failure. |
| Coturn is a free open source implementation of TURN and STUN Server. Prior to 4.17.0, turnports_allocate_even() in src/apps/relay/turn_ports.c marks the unused odd sibling port as TPS_TAKEN_ODD for an EVEN-PORT Allocate request with reservation bit R=0 even though no RTCP socket will release it, allowing an authenticated client to permanently exhaust the relay port pool and cause subsequent allocations to fail with STUN error 508. This issue is fixed in version 4.17.0. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/migrate_device: fix spinlock leak in migrate_vma_insert_huge_pmd_page
When check_stable_address_space() fails after the PMD spinlock has
been acquired via pmd_lock(), the code jumps directly to the abort
label, bypassing the spin_unlock() call in unlock_abort. This causes
the PMD spinlock to be permanently held, leading to a deadlock.
Change the goto target from abort to unlock_abort to ensure the
spinlock is always released on this error path. |
| Netty is a network application framework for development of protocol servers and clients. In netty-codec-http2 prior to versions 4.1.135.Final and 4.2.15.Final, the `DelegatingDecompressorFrameListener` class orchestrates HTTP/2 decompression by embedding a per-stream `EmbeddedChannel` that runs the appropriate decompression codec (gzip, deflate, zstd) and forwards decompressed chunks to a wrapped listener. Each decompressed chunk is a pooled `ByteBuf` handed to an anonymous `ChannelInboundHandlerAdapter` tail handler, which becomes the sole owner responsible for releasing it. A remote peer could send frames that would result in the flow-controller throwing and so trigger a resource leak which at the end might take down the whole JVM due OOME. Versions 4.1.135.Final and 4.2.15.Final patch the issue. |
| In the Linux kernel, the following vulnerability has been resolved:
staging: vme_user: fix location monitor leak in tsi148 bridge
tsi148_probe() allocates a location monitor resource and links it into
tsi148_bridge->lm_resources. The probe error path frees this list, but
tsi148_remove() only frees the dma, slave and master resource lists, so
the location monitor resource is leaked on device unbind or module
unload.
Free the lm_resources list in tsi148_remove() as well, before
tsi148_bridge is freed. |
| In the Linux kernel, the following vulnerability has been resolved:
net: hip04: fix RX buffer leak on build_skb failure
When build_skb() fails in hip04_rx_poll(), the driver jumps to the
refill path without releasing the current RX buffer and its DMA mapping.
Installing a replacement buffer then overwrites the slot references and
leaks both resources.
Keep the current slot intact and return budget so NAPI retries the same
buffer. Also free a newly allocated RX fragment when dma_map_single()
fails.
This issue was found by an in-house static analysis tool. |
| In the Linux kernel, the following vulnerability has been resolved:
firmware: stratix10-svc: fix memory leaks and list corruption bugs
Fix a memory leak when gen_pool_alloc() fails by freeing pmem on the error
path. Switch pmem allocation from devm_kzalloc() to kzalloc() with
explicit kfree() in the free path to match its list-managed lifetime.
Remove the erroneous list_del(&svc_data_mem) which corrupted the list head
on failed lookups. |
| In the Linux kernel, the following vulnerability has been resolved:
media: vivid: fix cleanup bugs in vivid_init()
When platform_device_register() fails in vivid_init(), the embedded
struct device in vivid_pdev has already been initialized by
device_initialize(), but the failure path jumps to free_output_strings
without dropping the device reference for the current platform device:
vivid_init()
-> platform_device_register(&vivid_pdev)
-> device_initialize(&vivid_pdev.dev)
-> setup_pdev_dma_masks(&vivid_pdev)
-> platform_device_add(&vivid_pdev)
This leads to a reference leak when platform_device_register() fails.
Fix this by calling platform_device_put() before jumping to the common
cleanup path.
Also, the unreg_driver label incorrectly calls
platform_driver_register() instead of platform_driver_unregister(),
which breaks cleanup when workqueue creation fails after successful
driver registration. Fix that as well.
The reference leak was identified by a static analysis tool I developed
and confirmed by manual review. The incorrect cleanup call was found
during code inspection. |
| In the Linux kernel, the following vulnerability has been resolved:
media: nuvoton: npcm-video: fix memory leaks in probe and remove
npcm_video_probe() allocates the npcm_video structure with kzalloc_obj()
but never frees it on any probe error path or in npcm_video_remove(),
leaking the allocation on every failed probe and every normal unbind.
Additionally, when npcm_video_setup_video() fails, the reserved memory
association established by of_reserved_mem_device_init() in
npcm_video_init() is not released, leaking the rmem_assigned_device
entry on the global list.
Fix both by adding kfree(video) to all probe error paths and to
npcm_video_remove(), and adding the missing
of_reserved_mem_device_release() call when npcm_video_setup_video()
fails. |
| In the Linux kernel, the following vulnerability has been resolved:
media: pci: dm1105: Free allocated workqueue
Destroy allocated workqueue in remove() callback to free its resources,
thus fixing memory leak. |
| In the Linux kernel, the following vulnerability has been resolved:
media: nxp: imx8-isi: Add missing v4l2_subdev_cleanup() in crossbar and pipe
Both mxc_isi_crossbar_init() and mxc_isi_pipe_init() call
v4l2_subdev_init_finalize() which allocates the subdev active state,
but neither mxc_isi_crossbar_cleanup() nor mxc_isi_pipe_cleanup()
calls v4l2_subdev_cleanup() to free it.
This causes a memory leak on every rmmod, reported by kmemleak:
unreferenced object 0xffff0000d06fc800 (size 192):

Add the missing v4l2_subdev_cleanup() calls before media_entity_cleanup()
in both crossbar and pipe cleanup paths. |
| In the Linux kernel, the following vulnerability has been resolved:
media: meson: vdec: Fix memory leak in error path of vdec_open
The vdec_open() function previously jumped directly to
err_m2m_release when vdec_init_ctrls() failed, skipping
release of the m2m context. This caused a resource leak.
Fix it by introducing a proper err_m2m_ctx_release label
that calls v4l2_m2m_ctx_release(sess->m2m_ctx) before
releasing the m2m device.
This was identified via kmemleak:

| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Release VFCT ACPI table reference
amdgpu_acpi_vfct_bios() fetches the VFCT table with acpi_get_table()
but never releases it. acpi_get_table() takes a reference on the
table (incrementing its validation_count and mapping it on the 0->1
transition); without a paired acpi_put_table() the mapping is leaked
on every call, whether or not a matching VBIOS image is found.
Route all exit paths after the table is acquired through a common
acpi_put_table(). The VBIOS image is copied out with kmemdup() before
the table is released, so it remains valid for the caller.
