| Vector | AV:L/AC:H/Au:S/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
The Linux kernel contains a flaw within the GFS2 filesystem related to self-recovery mechanisms. When a node withdraws and is the only node with the filesystem mounted, the system attempts to replay the local journal, which can lead to a NULL pointer dereference due to dereferencing an invalid memory location. This issue stems from attempting to access a journal inode after it has been freed. Removing the self-recovery functionality resolves the problem.
Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
