CVE-2011-3209 on Ubuntu 12.04 LTS (precise) - low.
Description:
The div_long_long_rem implementation in include/asm-x86/div64.h in the Linux kernel before 2.6.26 on the x86 platform allows local users to cause a denial of service (Divide Error Fault and panic) via a clock_gettime system call. Yasuaki Ishimatsu discovered a flaw in the kernel's clock implementation. A local unprivileged attacker could exploit this causing a denial of service.
