CVE-2012-6647

UnknownEPSS 0.38%

Last modified

CVE-2012-6647 is a vulnerability of currently unknown severity. The futex_wait_requeue_pi function in kernel/futex.c in the Linux kernel before 3.5.1 does not ensure that calls have two different futex addresses, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted FUTEX_WAIT_REQUEUE_PI command.. EPSS estimates a 0.38% chance of exploitation in the next 30 days.
