CVE-2014-3153 is a high-severity flaw (CVSS 7.8) affecting linux kernel, enterprise linux server aus, opensuse, reported as exploited in the wild. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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.

Why this priority

  • High severity
  • EPSS top 1%: very likely to be exploited
  • Exploited in the wild (CISA KEV)
  • Public exploit reference
  • On your watchlist

A fixed release or distro patch exists.
