CVE-2012-0810 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.. EPSS estimates a 0.38% chance of exploitation in the next 30 days.
