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

Description An issue exists in the btrfs file system where the last unlink trans field is not updated when removing a directory. This can lead to incorrect fsync behavior if a user performs an fsync on a directory after it has been removed while still holding a file descriptor for it. In specific scenarios involving directory removal and subsequent power failure, the log replay during the next filesystem mount may fail with an -EIO error due to a corrupt leaf with an invalid nlink.

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