Security Vulnerabilities
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: validate inline data i_size during inode read
When reading an inode from disk, ocfs2_validate_inode_block() performs
various sanity checks but does not validate the size of inline data. If
the filesystem is corrupted, an inode's i_size can exceed the actual
inline data capacity (id_count).
This causes ocfs2_dir_foreach_blk_id() to iterate beyond the inline data
buffer, triggering a use-after-free when accessing directory entries from
freed memory.
In the syzbot report:
- i_size was 1099511627576 bytes (~1TB)
- Actual inline data capacity (id_count) is typically <256 bytes
- A garbage rec_len (54648) caused ctx->pos to jump out of bounds
- This triggered a UAF in ocfs2_check_dir_entry()
Fix by adding a validation check in ocfs2_validate_inode_block() to ensure
inodes with inline data have i_size <= id_count. This catches the
corruption early during inode read and prevents all downstream code from
operating on invalid data.

In the Linux kernel, the following vulnerability has been resolved:
crypto: algif_aead - Fix minimum RX size check for decryption
The check for the minimum receive buffer size did not take the
tag size into account during decryption. Fix this by adding the
required extra length.

In the Linux kernel, the following vulnerability has been resolved:
crypto: af_alg - Fix page reassignment overflow in af_alg_pull_tsgl
When page reassignment was added to af_alg_pull_tsgl the original
loop wasn't updated so it may try to reassign one more page than
necessary.
Add the check to the reassignment so that this does not happen.
Also update the comment which still refers to the obsolete offset
argument.

In the Linux kernel, the following vulnerability has been resolved:
perf/x86/intel/uncore: Skip discovery table for offline dies
This warning can be triggered if NUMA is disabled and the system
boots with fewer CPUs than the number of CPUs in die 0.
WARNING: CPU: 9 PID: 7257 at uncore.c:1157 uncore_pci_pmu_register+0x136/0x160 [intel_uncore]
Currently, the discovery table continues to be parsed even if all CPUs
in the associated die are offline. This can lead to an array overflow
at "pmu->boxes[die] = box" in uncore_pci_pmu_register(), which may
trigger the warning above or cause other issues.
