CVE-2008-5300

Publication date 1 December 2008

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

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.

From the Ubuntu Security Team

Dann Frazier discovered that in certain situations sendmsg did not correctly release allocated memory. A local attacker could exploit this to force the system to run out of free memory, leading to a denial of service.
