High
| Vector | AV:N/AC:L/Au:N/C:P/I:P/A:P |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a NULL pointer dereference in the gfs2 log flush function. This occurs when outstanding glock work races with an unmount, specifically in the path from glock work func to gfs2 log flush through run queue, do xmote, and inode go sync. To prevent this, the code sets sdp->sd jdesc to NULL under the log flush lock in gfs2 jindex free and checks if sdp->sd jdesc is non-NULL before dereferencing it in gfs2 log flush.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
