The vulnerability is caused due to the kernel incorrectly setting the maximum stack size for 32bit applications in a 64bit environment, which can be exploited to e.g. trigger a "BUG()" or cause out-of-memory conditions via specially crafted applications. Successful exploitation requires a 64bit system. SOLUTION: Restrict access to trusted users only.
