A flaw was found in the GFS2 filesystems resource group lock management. A local attacker who is able to trigger actions on the gfs2 filesystem can possibly cause a use-after-free in which could possibly be abused by an attacker to crash the system, corrupt memory or escalate privileges on the system.
At this time there is no known mitigation for this flaw, but systems with updated kernels are not affected.
This bug is now closed. Further updates for individual products will be reflected on the CVE page(s):
