Description
IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a local attacker to cause kernel memory corruption due to insufficient validation. A crafted filesystem image can trigger an out-of-bounds kernel-stack write during directory reads, causing a system crash or potentially enabling privilege escalation.
