Description

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The ipc_rcu_putref function in ipc/util.c in the Linux kernel before 3.10 does not properly manage a reference count, which allows local users to cause a denial of service (memory consumption or system crash) via a crafted application.


Remediation

Install update from vendor's website.
