CVE-2011-1474 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. A locally locally exploitable DOS vulnerability was found in pax-linux versions 2.6.32.33-test79.patch, 2.6.38-test3.patch, and 2.6.37.4-test14.patch. A bad bounds check in arch_get_unmapped_area_topdown triggered by programs doing an mmap after a MAP_GROWSDOWN mmap will create an infinite loop condition without releasing the VM semaphore eventually leading to a system crash.. EPSS estimates a 0.35% chance of exploitation in the next 30 days.
