7.2 · HIGH
Published Sep 6, 2011 linux CWE-476 EPSS 0.38% (31th pctl)

Overview

CVE-2011-2184 is a high-severity vulnerability affecting linux linux_kernel. It was published on September 6, 2011 and has a CVSS 2.0 base score of 7.2 (HIGH).

This vulnerability has a CVSS 2.0 base score of 7.2, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical Description

The key_replace_session_keyring function in security/keys/process_keys.c in the Linux kernel before 2.6.39.1 does not initialize a certain structure member, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via a KEYCTL_SESSION_TO_PARENT argument to the keyctl function, a different vulnerability than CVE-2010-2960.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
