CVE-2011-3209

Published: 21 October 2011

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.

From the Ubuntu security team

Yasuaki Ishimatsu discovered a flaw in the kernel's clock implementation. A local unprivileged attacker could exploit this causing a denial of service.
