CVE-2012-1097: Linux Kernel

High severity, CVSS 7.8. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: before 3.0.24 (fixed in 3.0.24); from 3.1, before 3.2.10 (fixed in 3.2.10)
• Red Hat Enterprise Linux: version 4.0 only
• Red Hat Enterprise Mrg: version 2.0 only
• Suse Linux Enterprise Desktop: version 11 only
