Description

arch/mips/include/asm/thread_info.h in the Linux kernel before 3.14.8 on the MIPS platform does not configure _TIF_SECCOMP checks on the fast system-call path, which allows local users to bypass intended PR_SET_SECCOMP restrictions by executing a crafted application without invoking a trace or audit subsystem.

Affected products

Linux kernel: before 3.14.8 — fixed in 3.14.8

How to fix

Upgrade to a fixed version: Linux kernel 3.14.8. Check the vendor advisory for mitigations.
