Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A crash can occur in the Linux kernel when using overlay on top of btrfs. This happens because the
btrfs sync file() function incorrectly references the superblock from the dentry, which translates to the overlay's super block instead of the btrfs super block during fsid assignment.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
