CVE-2014-3153Exploited in the wildNVD status: Analyzed

Linux Kernel Privilege Escalation

Published Updated By the CyberSecBulletin desk

CVE-2014-3153 is a high-severity vulnerability in Linux Kernel from Linux, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists versions 3.2.60, 3.4.92, 3.10.42 as the first without the flaw, so updating Linux Kernel to one of those releases or later removes the exposure. CISA added it to the Known Exploited Vulnerabilities catalogue on May 25, 2022, which means attacks have been observed in the wild.

Patch now

Attackers are already exploiting this vulnerability, according to CISA.

What to do

  1. Update Linux Kernel to 3.2.60 or 3.4.92 or 3.10.42 or 3.12.22, whichever matches your release line, or a later version.
  2. CISA's required action: Apply updates per vendor instructions.

Official description

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.
