CVE-2010-0623 is a vulnerability of currently unknown severity. The futex_lock_pi function in kernel/futex.c in the Linux kernel before 2.6.33-rc7 does not properly manage a certain reference count, which allows local users to cause a denial of service (OOPS) via vectors involving an unmount of an ext3 filesystem.. EPSS estimates a 0.40% chance of exploitation in the next 30 days.
