arm64/efi: Avoid voluntary preemption with efi_mm installed
Gus reports a bad kernel memory access when using software PAN
(CONFIG_ARM64_SW_TTBR0_PAN=y) on a machine with support for EFI runtime
services:
Unable to handle kernel access to user memory outside uaccess routines

This is because the fpsimd context management code called from
__efi_fpsimd_begin() can preempt voluntarily, returning later to the EFI
code with an incorrect value for TTBR0_EL1 thanks to the deferred mm
switching used by the software PAN implementation.
Since EFI runtime services cannot preempt voluntarily and because the
fpsimd switching code does not rely on the TTBR0_EL1 mappings, simply
reorder the fpsimd switch so that it occurs before we change the
page-table. |
| In the Linux kernel, the following vulnerability has been resolved:
firewire: core: fix memory leak in error path of build_tree()
In the error path of build_tree(), node instances can remain in the local
linked list when the function returns.
Whenever an invalid value is detected in the self ID sequence, each
allocated node instance is either an entry in the linked list or an
entry in the ports array of its parent node. Therefore, the allocate
node instances can be safely released by traversing the linked list from
its head.
Release the remaining node instances with for_each_fw_node() before
returning to the caller. |
| In the Linux kernel, the following vulnerability has been resolved:
nfc: llcp: bound SNL TLV parsing to the skb and add length checks
nfc_llcp_recv_snl() walked the SNL TLV list using a u16 offset/length
pair derived from skb->len, without bounding reads to the actual skb
data. Three problems followed:
- For a short frame (skb->len < LLCP_HEADER_SIZE), tlv_len underflowed.
- The per-TLV header (type, length) was read without checking that two
bytes remained.
- A declared TLV length could run past the end of the buffer, and an
SDREQ with length == 0 made "service_name_len = length - 1" underflow
(size_t), driving an out-of-bounds read in the following strncmp() /
nfc_llcp_sock_from_sn(). The SDRES case likewise read tlv[2]/tlv[3]
without a length check.
A nearby NFC device can reach this without authentication; LLCP link
activation happens automatically after NFC-DEP.
Walk the TLV list by pointer, bounded by skb_tail_pointer() over the
linear skb data, and validate each TLV declared length before use. Add
explicit length checks for SDREQ (>= 1) and SDRES (exactly 2).

| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: validate ipc response length before dereferencing its fields
ipc_validate_msg() computes the expected message size by reading length
fields out of the response buffer supplied by the userspace ksmbd daemon
(payload_sz, session_key_len, ngroups, ...). Those fields are read before
the buffer is verified to be large enough to contain the struct they belong
to, so a short response makes the read land past the end of the allocation.
handle_response() sizes entry->response purely from the netlink attribute
length (nla_len()) and only guards the leading handle read, so the daemon
can install a response as small as the kmalloc-8 object seen below. When
ipc_msg_send_request() then calls ipc_validate_msg() for a
KSMBD_EVENT_RPC_REQUEST, the cast to struct ksmbd_rpc_command reads
resp->payload_sz at offset 8 of an 8-byte allocation:

| In the Linux kernel, the following vulnerability has been resolved:
smb: smbdirect: release pending child sockets outside the handler lock
smbdirect_socket_destroy() releases the listener's pending/ready child
sockets while still holding the listener's handler lock, the
&id_priv->handler_mutex taken via rdma_lock_handler(), not
sc->listen.lock, and before the listener's own rdma_destroy_id().
That ordering has one real consequence and one cosmetic one.
The real one: smbdirect_socket_release() drops the child's last
reference, which destroys the child's cm_id. Doing that before the
listener's rdma_destroy_id() lets _cma_cancel_listens(), running from
the listener's _destroy_id(), walk an already freed child id_priv,
which KASAN catches as a slab-use-after-free during listener shutdown:

The cosmetic one: releasing a child recurses into
smbdirect_socket_destroy(), which takes the child's own
rdma_lock_handler() lock nested under the listener's. The listener's
and the child's cm_id are always different instances, so this cannot
deadlock for real; the CM core itself nests a new connection id's
handler_mutex under the listening id's in cma_ib_req_handler(). But
lockdep only sees one lock class, reports possible recursive locking,
and then disables itself, hiding real locking bugs for the rest of the
run:

Splice the pending/ready children onto a local list under the
listener's listen.lock, while the handler lock is held so a concurrent
CM CONNECT_REQUEST cannot add more, but defer the actual
smbdirect_socket_release() calls until after the listener's cm_id has
been destroyed and its handler lock dropped. The children are
independent sockets whose teardown needs neither the listener's
handler lock nor its cm_id.
Found with ksmbdzzer [2], a KSMBD fuzzer that drives libFuzzer with a
kcov-dataflow [1] coverage vector: it folds each instrumented
comparison/argument's runtime operand value together with its PC (the
default arm mixes them as pc⊕val) so that a new operand value at a known
site counts as new coverage.

| In the Linux kernel, the following vulnerability has been resolved:
smb: smbdirect: free completion queues with ib_free_cq()
smbdirect_connection_destroy_qp() creates the send and receive completion
queues with ib_alloc_cq_any(), which for IB_POLL_WORKQUEUE arms an
internal completion handler that runs ib_cq_poll_work() on a workqueue.
Tearing those CQs down with ib_destroy_cq() frees them without first
cancelling that poll work.
If the provider posts a completion late -- for example Soft-RoCE (rxe)
posting an RNR error from rxe_receiver() after rdma_destroy_qp() -- the
handler re-queues ib_cq_poll_work() on the already-freed CQ, and a
follow-on access faults in rxe_req_notify_cq().
Use ib_free_cq(), which cancel_work_sync()es the poll work before freeing
the CQ, so no completion handler can run against a freed queue.

| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix slab-out-of-bounds read in ksmbd_alloc_user()
ksmbd_alloc_user() copies resp->hash_sz bytes out of the mountd IPC
login response with
user->passkey_sz = resp->hash_sz;
user->passkey = kmalloc(resp->hash_sz, KSMBD_DEFAULT_GFP);
if (user->passkey)
memcpy(user->passkey, resp->hash, resp->hash_sz);
resp->hash_sz is a __u16 supplied by the response, but resp->hash[] is
only KSMBD_REQ_MAX_HASH_SZ bytes. A malformed or malicious login
response can set hash_sz well beyond that (up to 65535), so the memcpy()
reads past the end of the response object. ipc_validate_msg() does not
bound hash_sz, so reject any response whose hash_sz exceeds the on-stack
hash[] buffer before allocating and copying.

| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: Do not skip lock checks for single-byte ranges
check_lock_range() uses inclusive ranges. Its callers pass the end
offset as start + length - 1, so start == end represents a valid
single-byte range rather than an empty range.
The start == end shortcut therefore skips mandatory byte-range lock
checks for one-byte reads, writes, copychunk operations and one-byte
truncate ranges. A conflicting lock covering that byte is not checked
and the operation is allowed to proceed.
Remove the shortcut. The truncate size == inode->i_size case is already
handled by only calling check_lock_range() when the new size differs
from the current file size. |
| In the Linux kernel, the following vulnerability has been resolved:
hwmon: (coretemp) Fix core_data leak on CPUs without PTS
pdata->core_data is allocated in init_temp_data() when the first core
temp_data of a package is created, but it is only released from
destroy_temp_data(), and only in the branch that handles the package
temp_data.
Package temp_data is created solely when the CPU supports
X86_FEATURE_PTS. On a CPU without it, coretemp_cpu_online() never calls
coretemp_add_core() with pkg_flag set, so pdata->pkg_data stays NULL.
coretemp_cpu_offline() then skips the removal of the package interface,
destroy_temp_data() is never called for package data, and the array is
still allocated when coretemp_device_remove() frees the platform data
that pointed at it.
Release the array in coretemp_device_remove(). destroy_temp_data() sets
pdata->core_data to NULL when it frees it, so the added kfree() is a
no-op on CPUs that do have PTS.
Tested on an Intel Core i5-1135G7. The driver was instrumented to log
every allocation and release of pdata->core_data, and the PTS check in
coretemp_cpu_online() was patched out to emulate a CPU without package
thermal support. Without this change the array was allocated and never
released, and coretemp_device_remove() still saw a non-NULL pointer.
With it the array is released and the pointer accounting balances. On an
unmodified build the release still happens via the package temp_data and
the added kfree() sees NULL, with no slab warnings over repeated module
load and unload cycles. |
| The LatePoint – Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.6.3 via the LatePointAbilityDeleteBooking::execute due to missing validation on a user controlled key. This makes it possible for attackers, with LatePoint Agent-level access and above, to read bookings and customer PII (full name, email, phone, and notes) assigned to other LatePoint agents, and delete arbitrary bookings by supplying any booking ID. This vulnerability is only exploitable when an administrator has enabled the Abilities API toggles (latepoint_abilities_api, latepoint_abilities_api_delete, and/or latepoint_abilities_api_edit) in the plugin settings. |
| The Photo Gallery by 10Web – Mobile-Friendly Image Gallery plugin for WordPress is vulnerable to time-based SQL Injection via 'album_id' Shortcode Attribute in all versions up to, and including, 1.8.44 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with author-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. An Author-level user can store a SQL injection payload inside a published post's shortcode attribute, causing the payload to execute when any visitor renders the post; notably, the unsanitized value appears on both sides of a UNION query, potentially doubling the observable time-based delay. |
| vm2 NodeVM versions before 3.12.1 contain a sandbox escape vulnerability where the DANGEROUS_BUILTINS denylist omits child_process despite blocking other host-spawning modules. Attackers can require child_process and execute arbitrary commands on the host system when NodeVM is configured with builtin:['*'] or explicit child_process allowance. |
| Incorrect authorization in ORB in Google Chrome prior to 153.0.8010.52 allowed a remote attacker to bypass site isolation via a crafted HTML page. (Chromium security severity: High) |
| The Deck config API allows authenticated users to set board-scoped configuration keys for arbitrary board IDs without validating whether the user owns or has permission to manage the referenced board. |
