CVE-2023-3212: Null Pointer Dereference

Published Jun 12, 2023
·
Updated

A flaw in the Linux Kernel found in the GFS2 file system. On corrupted gfs2 file systems the evict code can try to reference the journal descriptor structure, jdesc, after it has been freed and set to NULL. It can lead to null pointer dereference when gfs2transbegin being called and then fail ingfs2evictinode().

Other sources

A NULL pointer dereference issue was found in the gfs2 file system in the Linux kernel. It occurs on corrupt gfs2 file systems when the evict code tries to reference the journal descriptor structure after it has been freed and set to NULL. A privileged local user could use this flaw to cause a kernel panic.

— Launchpad

Linux Kernel is vulnerable to a denial of service, caused by NULL pointer dereference issue in the gfs2 file system. By sending a specially crafted request, a local authenticated attacker could exploit this vulnerability to cause a kernel panic.
