CVE-2010-3079: Canonical Ubuntu Linux

Medium severity, CVSS 5.5. EPSS: 0.4% chance of exploitation in the next 30 days.

kernel/trace/ftrace.c in the Linux kernel before 2.6.35.5, when debugfs is enabled, does not properly handle interaction between mutex possession and llseek operations, which allows local users to cause a denial of service (NULL pointer dereference and outage of all function tracing files) via an lseek call on a file descriptor associated with the set_ftrace_filter file.

Affected products

• Canonical Ubuntu Linux: version 9.10 only; version 10.04 only; version 10.10 only
• Linux Linux Kernel: before 2.6.35.5 (fixed in 2.6.35.5)
• Suse Linux Enterprise Desktop: version 11 only
• Suse Linux Enterprise High Availability Extension: version 11 only
