| In the Linux kernel, the following vulnerability has been resolved:
accel/ivpu: Add bounds check for firmware runtime memory
Validate that the firmware runtime memory specified in the image
header is properly aligned and sized to hold the firmware image.
This prevents errors during memory allocation and image transfer. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: revalidate bridge ports
ebt_redirect_tg() dereferences br_port_get_rcu() return without a
NULL check, causing a kernel panic when the bridge port has been
removed between the original hook invocation and an NFQUEUE
reinject.
A mere NULL check isn't sufficient, however. As sashiko review
points out userspace can not only remove the port from the bridge,
it could also place the device in a different virtual device, e.g.
macvlan.
If this happens, we must drop the packet, there is no way for us to
reinject it into the bridge path.
Switch to _upper API, we don't need the bridge port structure.
Also, this fix keeps another bug intact:
Both nfnetlink_log and nfnetlink_queue use CONFIG_BRIDGE_NETFILTER
too aggressive, which prevents certain logging features when queueing
in bridge family: NETFILTER_FAMILY_BRIDGE can be enabled while the old
CONFIG_BRIDGE_NETFILTER cruft is off.
Fixes tag is a common ancestor, this was always broken. |

drm/amd/display: Fix NULL deref and buffer over-read in SDP debugfs
[Why & How]
dp_sdp_message_debugfs_write() dereferences connector->base.state->crtc
without checking for NULL. A connector can be connected but not bound to
any CRTC (e.g. after hot-plug before the next atomic commit), causing a
kernel crash when writing to the sdp_message debugfs node.
The function also ignores the user-provided size argument and always
passes 36 bytes to copy_from_user(), reading past the user buffer when
size < 36.
Fix both issues by:
- Returning -ENODEV when connector->base.state or state->crtc is NULL
- Clamping write_size to min(size, sizeof(data))

| In the Linux kernel, the following vulnerability has been resolved:
firmware: stratix10-rsu: Fix NULL deref on rsu_send_msg() timeout in probe
rsu_send_msg() can return -ETIMEDOUT when
wait_for_completion_interruptible_timeout() fires while the SMC call is still
pending. In stratix10_rsu_probe(), the error paths for COMMAND_RSU_DCMF_VERSION,
COMMAND_RSU_DCMF_STATUS, COMMAND_RSU_MAX_RETRY and COMMAND_RSU_GET_SPT_TABLE
call stratix10_svc_free_channel() - which sets chan->scl to NULL - but then
fall through and queue the next request on the same channel. The next svc
kthread that runs will dereference pdata->chan->scl in its receive callback
path, triggering a NULL pointer dereference identical to the one fixed by
commit c45f7263100c ("firmware: stratix10-rsu: Fix NULL pointer dereference
when RSU is disabled") for the COMMAND_RSU_STATUS path.
Apply the same cleanup pattern to the remaining failure paths: remove the
async client, free the channel, and return early so no further messages are
queued on a channel whose scl has been cleared.
While at it, clean up stratix10_rsu_probe() in two ways without changing
behavior:
- Drop redundant zero-initialization of fields already cleared by
devm_kzalloc(): client.receive_cb, status.* and spt0/1_address
(INVALID_SPT_ADDRESS is 0x0).
- Replace five identical 3-line error-cleanup blocks
(stratix10_svc_remove_async_client() + stratix10_svc_free_channel() +
return ret) with goto labels (remove_async_client, free_channel),
matching the standard kernel resource-unwinding pattern and making it
easier to extend the probe sequence without forgetting matching
cleanup.
Also move init_completion() next to mutex_init() so sync-primitive
initialization is grouped before anything that could trigger a
callback.
---
v2: Add a minor clean-up of the function stratix10_rsu_probe() to have a
centralize exit for all the rsu_send_async_msg() and rsu_send_msg(). |
| Versions of the package jsrsasign before 11.1.1 are vulnerable to Infinite loop via the bnModInverse function in ext/jsbn2.js when the BigInteger.modInverse implementation receives zero or negative inputs, allowing an attacker to hang the process permanently by supplying such crafted values (e.g., modInverse(0, m) or modInverse(-1, m)). |
| In the Linux kernel, the following vulnerability has been resolved:
thunderbolt: Bound root directory content to block size
__tb_property_parse_dir() does not check that content_offset +
content_len fits within block_len for the root directory case.
When rootdir->length equals or exceeds block_len - 2, the entry
loop reads past the allocated property block.
Add a bounds check after computing content_offset and content_len
to reject directories whose content extends past the block. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Clamp HDMI HDCP2 rx_id_list read to buffer size
[Why & How]
During HDCP 2.x repeater authentication over HDMI, the driver reads the
sink's RxStatus register and extracts a 10-bit message size field (max
value 1023). This value is used as the read length for the ReceiverID
list without being clamped to the size of the destination buffer
rx_id_list[177]. A malicious HDMI repeater could advertise a message
size larger than the buffer, causing an out-of-bounds write during the
I2C read.
Clamp the read length in mod_hdcp_read_rx_id_list() to the size of the
rx_id_list buffer, matching the approach already used in the DP branch.

| In the Linux kernel, the following vulnerability has been resolved:
futex/requeue: Prevent NULL pointer dereference in remove_waiter() on self-deadlock
When FUTEX_CMP_REQUEUE_PI requeues a non-top waiter that already owns the
target PI futex, task_blocks_on_rt_mutex() returns -EDEADLK before setting
waiter->task.
The subsequent remove_waiter() in rt_mutex_start_proxy_lock() dereferences
the NULL waiter->task, causing a kernel crash.
Add a self-deadlock check for non-top waiters before calling
rt_mutex_start_proxy_lock(), analogous to the top-waiter check in
futex_lock_pi_atomic(). |
| In the Linux kernel, the following vulnerability has been resolved:
mm/huge_memory: use correct flags for device private PMD entry
Commit 65edfda6f3f2 ("mm/rmap: extend rmap and migration support
device-private entries") updated set_pmd_migration_entry() to use
pmdp_huge_get_and_clear() in the softleaf case, but made no further
adjustments to the function itself.
Therefore this function continues to incorrectly use pmd_write(),
pmd_soft_dirty() and pmd_uffd_wp() to determine whether the installed
migration entry should be marked writable, softdirty or uffd-wp
respectively.
Whilst all are incorrect, the most problematic of these is pmd_write(), as
this can lead to corrupted rmap state.
On x86-64 _PAGE_SWP_SOFT_DIRTY is aliased to _PAGE_RW. So calling
pmd_write() on a softleaf will return the softdirty state encoded in the
entry, assuming CONFIG_MEM_SOFT_DIRTY was enabled.
This was observed when running the hmm.hmm_device_private.anon_write_child
selftest:
1. The test faults in a range then migrates it such that a device-private
THP range is established.
2. The parent then migrates it to a device-private writable PMD entry whose
folio is entirely AnonExclusive with entire_mapcount=1, softdirty set
(accidentally correct write state).
3. The parent forks and the PMD entries are set to device-private read only
entries, entire_mapcount=2, softdirty still set.
4. [BUG] The child writes to the range then migrates to RAM - intending to
install non-writable migration entries - but replacing parent and child
PMD mappings with WRITABLE entries due to misinterpreting the softdirty
bit.
5. In remove_migration_pmd(), if !softleaf_is_migration_read(entry) we
set the RMAP_EXCLUSIVE flag when calling folio_add_anon_rmap_pmd() for
both parent and child, which are therefore AnonExclusive.
6. [SPLAT] Child sets migrated folio entire_mapcount=1, parent sets
entire_mapcount=2 and we end up with an AnonExclusive folio with
entire_mapcount=2! Assert fires in __folio_add_anon_rmap():
VM_WARN_ON_FOLIO(folio_test_large(folio) &&
folio_entire_mapcount(folio) > 1 &&
PageAnonExclusive(cur_page), folio)
This patch fixes the issue by correctly referencing the softleaf entry
fields for writable, softdirty and uffd-wp in set_pmd_migration_entry().
It also only updates A/D flags if the entry is present as these are
otherwise not meaningful for a softleaf entry.
This patch also flips the if (!present) { ... } else { ... } logic in
set_pmd_migration_entry() so it is easier to understand, and adds some
comments to make things clearer.
I was able to bisect this to commit 775465fd26a3 ("lib/test_hmm: add zone
device private THP test infrastructure") which first exposes this bug as
it was the commit that permitted test_hmm to generate the test.
However commit 65edfda6f3f2 ("mm/rmap: extend rmap and migration support
device-private entries") is the commit that actually enabled this
behaviour. |
| Rclone is a command-line program to sync files and directories to and from different cloud storage providers. From 1.46.0 until 1.74.3, rclone rcd --rc-serve accepts unauthenticated GET and HEAD requests to paths of the form: /[remote:path]/object. The remote value is parsed from the URL and passed to normal backend initialization. Inline remote configuration can set backend options that execute local commands during initialization. As a result, a single unauthenticated GET or HEAD request can execute a command as the rclone process user. This vulnerability is fixed in 1.74.3. |

drm/v3d: Fix global performance monitor reference counting
In the SET_GLOBAL ioctl, v3d_perfmon_find() bumps the reference count on
the perfmon it returns, but v3d_perfmon_set_global_ioctl() and
v3d_perfmon_delete() fail to release that reference on several paths:
1. v3d_perfmon_set_global_ioctl() leaks the reference on its error
paths.
2. CLEAR_GLOBAL leaks both the find reference and the reference
previously stashed in v3d->global_perfmon by the SET_GLOBAL ioctl
that configured it.
3. Destroying a perfmon that is the current global perfmon leaks the
reference stashed by the SET_GLOBAL ioctl.
Release each of these references explicitly. |

drm/amdkfd: fix NULL dereference in get_queue_ids()
When usr_queue_id_array is NULL and num_queues is non-zero,
get_queue_ids() returns NULL. The callers check only IS_ERR() on the
return value; since IS_ERR(NULL) == false the check passes, and
suspend_queues() calls q_array_invalidate() which immediately
dereferences NULL while iterating num_queues times.
Userspace can trigger this via kfd_ioctl_set_debug_trap() by supplying
num_queues > 0 with a zero queue_array_ptr, causing a kernel panic.
A NULL usr_queue_id_array with num_queues == 0 is a legitimate no-op
(q_array_invalidate never executes, and resume_queues already guards
all queue_ids dereferences behind a NULL check). Return ERR_PTR(-EINVAL)
only when num_queues is non-zero and the pointer is absent; both callers
already propagate IS_ERR() returns correctly to userspace.

Revert "drm/xe: Skip exec queue schedule toggle if queue is idle during suspend"
This reverts commit 8533051ce92015e9cc6f75e0d52119b9d91610b6.
The idle-skip optimization bypasses GuC suspend, so the GPU may not
perform the context switch that flushes TLB entries for invalidated
userptr VMAs. In LR/preempt-fence VM mode, this can lead to missed TLB
invalidation and page faults during userptr invalidation tests.
Restore unconditional schedule toggling on suspend so the context-switch
TLB flush is always performed.
This optimization will be reintroduced with a fix that does not skip
suspend in LR/preempt-fence VM mode.
