Doc Text:	A flaw was found in the Linux kernel’s system-call auditing support(CONFIG_AUDITSYSCALL) for 32-bit platforms. It is vulnerable to a crash caused by erroneous handling of bad system call numerals. This issue occurs during syscall(2) calls if system-call auditing is enabled on the system. This flaw allows an unprivileged user or process to crash the system kernel, resulting in a denial of service. The highest threat from this vulnerability is system availability.	Story Points:	---

Description Prasad Pandit 2014-06-20 13:10:48 UTC

Linux kernel built with the system-call auditing support(CONFIG_AUDITSYSCALL)
for 32-bit platforms is vulnerable to a crash caused by erroneous handling of
bad system call numerals. It occurs during syscall(2) calls, if system-call
auditing is enabled on the system.

An unprivileged user/process could use this flaw to crash the system kernel
resulting in DoS.
