Linux kernel hugetlbfs denial of service

kernel-hugetlbfs-dos (36925) The risk level is classified as LowLow Risk

Description:

Linux kernel is vulnerable to a denial of service, caused by a misconversion error in hugetlbfs. A local attacker could exploit this vulnerability to cause a kernel panic, resulting in a denial of service.

Remedy:

For Debian Linux (linux-2.6):
Refer to DSA-1381-1 for patch, upgrade, or suggested workaround information. See References.

For other distributions:
Contact your vendor for patch or upgrade information. See References.
