CVE-2012-2133

Publication date 24 April 2012

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

Use-after-free vulnerability in the Linux kernel before 3.3.6, when huge pages are enabled, allows local users to cause a denial of service (system crash) or possibly gain privileges by interacting with a hugetlbfs filesystem, as demonstrated by a umount operation that triggers improper handling of quota data.

From the Ubuntu Security Team

Schacher Raindel discovered a flaw in the Linux kernel's memory handling when hugetlb is enabled. An unprivileged local attacker could exploit this flaw to cause a denial of service and potentially gain higher privileges.
