Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.8.9
Description
The issue is related to the btrfs file system in the Linux kernel. It was discovered that the kernel did not properly set the WRITTEN flag on all metadata blocks, which could lead to corruption on disk and out-of-bounds access. This was reported by KASAN as a wild-memory-access. The vulnerability was hit on a crafted image tweaking the WRITTEN bit.
Recommendations
To resolve the issue, upgrade the Linux kernel to version 6.8.9 or later. This will ensure that the WRITTEN flag is properly set on all metadata blocks, preventing potential corruption and out-of-bounds access.
