Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.43
Description
The vulnerability is related to a potential parallel list adding issue in the btrfs reclaim bgs work function, which can cause list corruption and trigger a kernel bug. The issue can be reproduced when relocation cannot find more chunk space and ends with ENOSPC. The vulnerability is fixed by taking the fs info->unused bgs lock.
Recommendations
To resolve the issue, update the Linux kernel to version 6.6.43 or later. If updating is not possible, consider taking the fs info->unused bgs lock to prevent parallel list adding and list corruption. However, this is a temporary workaround and updating the kernel is the recommended solution.
At the moment, there is no information about other versions that contain a fix for this vulnerability.
