Last modified Jun 16, 2026

CVE-2012-1097 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. The regset (aka register set) feature in the Linux kernel before 3.2.10 does not properly handle the absence of .get and .set methods, which allows local users to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via a (1) PTRACE_GETREGSET or (2) PTRACE_SETREGSET ptrace call.. EPSS estimates a 0.35% chance of exploitation in the next 30 days.
