CVE-2012-0810: Linux Kernel

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

The int3 handler in the Linux kernel before 3.3 relies on a per-CPU debug stack, which allows local users to cause a denial of service (stack corruption and panic) via a crafted application that triggers certain lock contention.
