arch/x86/kernel/entry_64.S in the Linux kernel before 3.19.2 does not
prevent the TS_COMPAT flag from reaching a user-mode task, which might
allow local users to bypass the seccomp or audit protection mechanism via a
crafted application that uses the (1) fork or (2) close system call, as
demonstrated by an attack against seccomp before 3.16.
