ISS X-Force Database: linux-kernel-dnotify-privilege-escalation(42131): Linux kernel dnotify privilege escalation

Linux kernel dnotify privilege escalation

linux-kernel-dnotify-privilege-escalation (42131)

High Risk

Description:

Linux kernel could allow a local attacker to gain elevated privileges on the system, caused by a race condition error in the dnotify subsystem between the fcntl() and close() calls. An attacker could exploit this vulnerability to gain root privileges or cause the system to crash.
