1) Missing release of memory after effective lifetime

EUVDB-ID: #VU95244

Risk: Low

CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2005-3181

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

The vulnerability allows a local user to perform service disruption.

The audit system in Linux kernel 2.6.6, and other versions before 2.6.13.4, when CONFIG_AUDITSYSCALL is enabled, uses an incorrect function to free names_cache memory, which prevents the memory from being tracked by AUDITSYSCALL code and leads to a memory leak that allows attackers to cause a denial of service (memory consumption).

Mitigation

Install update from vendor's repository.

Vulnerable software versions

Linux kernel: All versions
