| In the Linux kernel, the following vulnerability has been resolved:
media: i2c: ov8856: free control handler on error in ov8856_init_controls()
The control handler wasn't freed if adding controls failed, add an error
exit label and convert the existing error return to use it. |

drm/colorop: Fix blob property reference tracking in state lifecycle
The colorop state blob property handling had memory leaks during state
duplication, destruction, and reset operations. The implementation
failed to follow the established pattern from drm_crtc's handling of
DEGAMMA/GAMMA blob properties.
Issues fixed:
- drm_colorop_atomic_destroy_state() was freeing state memory without
releasing the blob reference, causing a leak
- drm_colorop_reset() was directly freeing old state with kfree()
instead of properly destroying it, leaking blob references
- drm_colorop_cleanup() had duplicate blob cleanup code
Changes:
- Add __drm_atomic_helper_colorop_destroy_state() helper to properly
release blob references before freeing state memory
- Update drm_colorop_atomic_destroy_state() to call the helper
- Fix drm_colorop_reset() to use drm_colorop_atomic_destroy_state()
for proper cleanup of old state
- Simplify drm_colorop_cleanup() to use the common destruction path
This matches the well-tested pattern used by drm_crtc since 2016 and
ensures proper reference counting throughout the state lifecycle.

| In the Linux kernel, the following vulnerability has been resolved:
drm/msm: always recover the gpu
Previously, in case there was no more work to do, recover worker
wouldn't trigger recovery and would instead rely on the gpu going to
sleep and then resuming when more work is submitted.
Recover_worker will first increment the fence of the hung ring so, if
there's only one job submitted to a ring and that causes an hang, it
will early out.
There's no guarantee that the gpu will suspend and resume before more
work is submitted and if the gpu is in a hung state it will stay in that
state and probably trigger a timeout again.
Just stop checking and always recover the gpu.

drm/amdgpu/vce: Prevent partial address patches
In the case that only one of lo/hi is valid, the patching could result
in a bad address written to in FW. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: zero-initialize GART table on allocation
GART TLB is flushed after unmapping but not after mapping. Since
amdgpu_bo_create_kernel() does not zero-initialize the buffer, when a
single PTE is written the TLB may speculatively load other uninitialized
entries from the same cacheline. Those garbage entries can appear valid,
and a subsequent write to another PTE in the same cacheline may cause the
GPU to use a stale garbage PTE from the TLB.
Fix this by calling memset_io() to zero-initialize the GART table with
gart_pte_flags immediately after allocation.
Using AMDGPU_GEM_CREATE_VRAM_CLEARED, SDMA-based clear will not work
since SDMA needs GART to be initialized to work.

| In the Linux kernel, the following vulnerability has been resolved:
mm/vma: do not try to unmap a VMA if mmap_prepare() invoked from mmap()
The mmap_prepare hook functionality includes the ability to invoke
mmap_prepare() from the mmap() hook of existing 'stacked' drivers, that is
ones which are capable of calling the mmap hooks of other drivers/file
systems (e.g. overlayfs, shm).
As part of the mmap_prepare action functionality, we deal with errors by
unmapping the VMA should one arise. This works in the usual mmap_prepare
case, as we invoke this action at the last moment, when the VMA is
established in the maple tree.
However, the mmap() hook passes a not-fully-established VMA pointer to the
caller (which is the motivation behind the mmap_prepare() work), which is
detached.
So attempting to unmap a VMA in this state will be problematic, with the
most obvious symptom being a warning in vma_mark_detached(), because the
VMA is already detached.
It's also unncessary - the mmap() handler will clean up the VMA on error.
So to fix this issue, this patch propagates whether or not an mmap action
is being completed via the compatibility layer or directly.
If the former, then we do not attempt VMA cleanup, if the latter, then we
do.
This patch also updates the userland VMA tests to reflect the change. |

iommu/vt-d: Block PASID attachment to nested domain with dirty tracking
Kernel lacks dirty tracking support on nested domain attached to PASID,
fails the attachment early if nesting parent domain is dirty tracking
configured, otherwise dirty pages would be lost. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/ionic: bound node_desc sysfs read with %.64s
node_desc[64] in struct ib_device is not guaranteed to be NUL-
terminated. The core IB sysfs handler uses "%.64s" for exactly this
reason (drivers/infiniband/core/sysfs.c:1307), since node_desc_store()
performs a raw memcpy of up to IB_DEVICE_NODE_DESC_MAX bytes with no NUL
termination:
memcpy(desc.node_desc, buf, min_t(int, count, IB_DEVICE_NODE_DESC_MAX));
If exactly 64 bytes are written via the node_desc sysfs file, the array
contains no NUL byte. The ionic hca_type_show() handler uses unbounded
"%s" and will read past the end of node_desc into adjacent fields of
struct ib_device until it encounters a NUL.
ionic supports IB_DEVICE_MODIFY_NODE_DESC, so this is triggerable by
userspace.
Match the core handler and bound the format specifier. |

perf/x86/intel: Improve validation and configuration of ACR masks
Currently there are several issues on the user space ACR mask validation
and configuration.
- The validation for user space ACR mask (attr.config2) is incomplete,
e.g., the ACR mask could include the index which belongs to another
ACR events group, but it's not validated.
- An early return on an invalid ACR mask caused all subsequent ACR groups
to be skipped.
- The stale hardware ACR mask (hw.config1) is not cleared before setting
new hardware ACR mask.
The following changes address all of the above issues.
- Figure out the event index group of an ACR group. Any bits in the
user-space mask not present in the index group are now dropped.
- Instead of an early return on invalid bits, drop only the invalid
portions and continue iterating through all ACR events to ensure full
configuration.
- Explicitly clear the stale hardware ACR mask for each event prior to
writing the new configuration.
Besides, a non-leader event member of ACR group could be disabled in
theory. This could cause bit-shifting errors in the acr_mask of remaining
group members. But since ACR sampling requires all events to be active,
this should not be a big concern in real use case. Add a "FIXME" comment
to notice this risk. |
| In the Linux kernel, the following vulnerability has been resolved:
udf: reject descriptors with oversized CRC length
udf_read_tagged() skips CRC verification when descCRCLength +
sizeof(struct tag) exceeds the block size. A crafted UDF image can
set descCRCLength to an oversized value to bypass CRC validation
entirely; the descriptor is then accepted based solely on the 8-bit
tag checksum, which is trivially recomputable.
Reject such descriptors instead of silently accepting them. A
legitimate single-block descriptor should never have a CRC length that
exceeds the block. |

f2fs: fix fsck inconsistency caused by incorrect nat_entry flag usage
f2fs_need_dentry_mark() reads nat_entry flags without mutual exclusion
with the checkpoint path, which can result in an incorrect inode block
marking state. The scenario is as follows:
create & write & fsync 'file A' write checkpoint
- f2fs_do_sync_file // inline inode
- f2fs_write_inode // inode folio is dirty
- f2fs_write_checkpoint
- f2fs_flush_merged_writes
- f2fs_sync_node_pages
- f2fs_fsync_node_pages // no dirty node
- f2fs_need_inode_block_update // return true
- f2fs_fsync_node_pages // inode dirtied
- f2fs_need_dentry_mark //return true
- f2fs_flush_nat_entries
- f2fs_write_checkpoint end
- __write_node_folio // inode with DENT_BIT_SHIFT set
SPO, "fsck --dry-run" find inode has already checkpointed but still
with DENT_BIT_SHIFT set
The state observed by f2fs_need_dentry_mark() can differ from the state
observed in __write_node_folio() after acquiring sbi->node_write. The
root cause is that the semantics of IS_CHECKPOINTED and
HAS_FSYNCED_INODE are only guaranteed after the checkpoint write has
fully completed.
This patch moves set_dentry_mark() into __write_node_folio() and
protects it with the sbi->node_write lock. |

selinux: fix avdcache auditing
The per-task avdcache was incorrectly saving and reusing the
audited vector computed by avc_audit_required() rather than
recomputing based on the currently requested permissions and
distinguishing the denied versus allowed cases. As a result,
some permission checks were not being audited, e.g.
directory write checks after a previously cached directory
search check.
