CVE-2014-9922 [HIGH] CWE-122 kernel: Privilege escalation in eCryptfs subsystem via a large filesystem stack
kernel: Privilege escalation in eCryptfs subsystem via a large filesystem stack
The eCryptfs subsystem in the Linux kernel before 3.18 allows local users to gain privileges via a large filesystem stack that includes an overlayfs layer, related to fs/ecryptfs/main.c and fs/overlayfs/super.c.
A flaw was discovered in the way the kernel allows stackable filesystems to overlay. A local attacker who is able to mount filesystems can abuse this flaw to escalate privileges.
