TITLE:
Linux Kernel MIPS Syscall Denial of Service

SECUNIA ADVISORY ID:
SA33078

VERIFY ADVISORY:
http://secunia.com/advisories/33078/

CRITICAL:
Not critical

IMPACT:
DoS

WHERE:
Local system

OPERATING SYSTEM:
Linux Kernel 2.6.x
http://secunia.com/advisories/product/2719/

DESCRIPTION:
A vulnerability has been reported in the Linux Kernel, which can be
exploited by malicious, local users to cause a DoS (Denial of
Service).

The vulnerability is caused due to an out of bounds array access in
arch/mips/kernel/scall64-o32.S. This can be exploited to e.g. crash a
vulnerable system by making a syscall with a syscall number of less
than 4000.

Successful exploitation requires a 64bit MIPS architecture.

SOLUTION:
Fixed in the GIT repository.
