Vulnerability details

The vulnerability allows a local user to perform a denial of service (DoS) attack.

Linux kernel 2.6.28 allows local users to cause a denial of service ('soft lockup' and process loss) via a large number of sendmsg function calls, which does not block during AF_UNIX garbage collection and triggers an OOM condition, a different vulnerability than CVE-2008-5029.
