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.
