CVE-2015-2830 (retired)

Priority
Description
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.
Ubuntu-Description
A privilege escalation was discovered in the fork syscall via the int80
entry on 64 bit kernels with 32 bit emulation support. An unprivileged
local attacker could exploit this flaw to increase their privileges on the
system.
