Linux Kernel Privilege Escalation Vulnerability

KEVHIGH 7.8EPSS 37.2%

Does this matter?

Known to be exploited in the wild (CISA KEV, CISA remediation deadline 15 June 2022). Treat as an emergency change: patch or isolate now, then hunt for prior compromise.

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.
