CVE-2012-1146: Fedoraproject Fedora

Medium severity, CVSS 5.5. EPSS: 0.5% chance of exploitation in the next 30 days.

The mem_cgroup_usage_unregister_event function in mm/memcontrol.c in the Linux kernel before 3.2.10 does not properly handle multiple events that are attached to the same eventfd, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by registering memory threshold events.

Affected products

• Fedoraproject Fedora: version 16 only
• Linux Linux Kernel: before 3.2.10 (fixed in 3.2.10)
• Suse Linux Enterprise Desktop: version 11 only
• Suse Linux Enterprise High Availability Extension: version 11 only
• Suse Linux Enterprise Server: version 11 only
