CVE-2013-1958: Linux Kernel

Low severity, CVSS 1.9. EPSS: 0.3% chance of exploitation in the next 30 days.

The scm_check_creds function in net/core/scm.c in the Linux kernel before 3.8.6 does not properly enforce capability requirements for controlling the PID value associated with a UNIX domain socket, which allows local users to bypass intended access restrictions by leveraging the time interval during which a user namespace has been created but a PID namespace has not been created.

Affected products

• Linux Linux Kernel: up to and including 3.8.5; version 3.8.0 only; version 3.8.1 only; version 3.8.2 only; version 3.8.3 only; version 3.8.4 only
