Last modified
CVE-2009-2767 is a vulnerability of currently unknown severity. The init_posix_timers function in kernel/posix-timers.c in the Linux kernel before 2.6.31-rc6 allows local users to cause a denial of service (OOPS) or possibly gain privileges via a CLOCK_MONOTONIC_RAW clock_nanosleep call that triggers a NULL pointer dereference.. EPSS estimates a 0.74% chance of exploitation in the next 30 days.
