Description Vasyl Kaigorodov 2014-05-29 04:51:58 EDT 
Linux kernel built with the system-call auditing support(CONFIG_AUDITSYSCALL) is vulnerable to a kernel crash or information disclosure flaw caused by out of bounds memory access. It could occur when system call audit rules are configured on a system. Administrative privileges are required to add such audit rules.

When system call audit rules are present on a system, an unprivileged user/program could use this flaw to leak kernel memory bytes or crash the system resulting DoS.
