CVE-2024-43885

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to a double inode unlock for direct IO sync writes in the btrfs file system. When a direct IO sync write is performed at btrfs sync file(), and inode logging needs to be skipped or an error occurs during transaction start or delalloc flushing, the inode is unlocked under the 'out release extents' label and then again at btrfs direct write(). This is fixed by checking if inode unlocking should be skipped under that label.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
