Description

The kernel packages contain the Linux kernel, the core of any Linux operating system.

This update fixes the following security issue:

  • It was found that the RHSA-2010:0178 update did not correctly fix the CVE-2009-4307 issue, a divide-by-zero flaw in the ext4 file system code. A local, unprivileged user with the ability to mount an ext4 file system could use this flaw to cause a denial of service. (CVE-2012-2100, Low)

This update also fixes several bugs. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section.

Users should upgrade to these updated packages, which contain backported patches to correct this issue, and fix the bugs noted in the Technical Notes. The system must be rebooted for this update to take effect.
