- Summary
- CVE-2026-23388 affecting package kernel for versions less than 6.6.130.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
Squashfs: check metadata block offset is within range
Syzkaller reports a "general protection fault in squashfs_copy_data"
This is ultimately caused by a corrupted index look-up table, which produces a negative metadata block offset.
This is subsequently passed to squashfs_copy_data (via squashfs_read_metadata) where the negative offset causes an out of bounds access.
The fix is to check that the offset is within range in squashfs_read_metadata. This will trap this and other cases.
