CVE-2013-4300
The scm_check_creds function in net/core/scm.c in the Linux kernel before 3.11 performs a capability check in an incorrect namespace, which allows local users to gain privileges via PID spoofing.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.42%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
