Linux Kernel Futex Local Privilege Escalation (CVE-2014-3153)

  Severity: LOW
  CVE Identifier: CVE-2014-3153
  Advisory Date: JUL 16, 2015


The futex_requeue function in kernel/futex.c in the Linux kernel through 3.14.5 does not ensure that calls have two different futex addresses, which allows local users to gain privileges via a crafted FUTEX_REQUEUE command that facilitates unsafe waiter modification.
