Last modified

CVE-2014-3153 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. 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.. CISA has confirmed active exploitation in the wild. EPSS estimates a 37.23% chance of exploitation in the next 30 days.
