Linux Kernel 'sendmsg()' Local Denial of Service Vulnerability

The Linux kernel is prone to a local denial-of-service vulnerability.

Attackers can exploit this issue to create a soft lockup of the vulnerable kernel or to invoke the 'oom-killer' kernel functionality, which may halt unrelated processes. This may result in a denial-of-service condition.

NOTE: This issue was either caused or revealed by the fix for BID 32154 (Linux Kernel '__scm_destroy()' Local Denial of Service Vulnerability).

The Linux kernel 2.6.27 and prior versions are affected.
