Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A slab-use-after-free issue exists in the gfs2 component. During filesystem shutdown, quota data objects were freed synchronously without being removed from the Least Recently Used (LRU) list, leading to LRU list corruption. This results in a use-after-free condition when the shrinker function
gfs2 qd shrink scan() attempts to access objects that have already been freed. The issue is triggered within the qd put() function.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
