Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a data race condition within the
gfs2 show options() function. Specifically, fields within the gfs2 tune structure, such as gt logd secs, are accessed without acquiring the necessary gt spin lock. This can lead to data races when gfs2 show options() and other functions, like gfs2 reconfigure(), are executed concurrently. The issue is resolved by acquiring the sdp->sd tune.gt spin lock before accessing these fields and releasing it afterward.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
