CVE-2011-2521

Publication date 24 May 2012

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

The x86_assign_hw_event function in arch/x86/kernel/cpu/perf_event.c in the Performance Events subsystem in the Linux kernel before 2.6.39 does not properly calculate counter values, which allows local users to cause a denial of service (panic) via the perf program.
