Vulnerability identifier: #VU99924

Vulnerability 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]

CWE-ID: CWE-399

Exploitation vector: Local

Exploit availability: No

Vulnerable software:
Linux kernel
Operating systems & Components / Operating system

Description

The vulnerability allows a local user to perform service disruption.

The Linux kernel 2.6 before 2.6.12.1 allows local users to cause a denial of service (kernel panic) via a non group-leader thread executing a different program than was pending in itimer, which causes the signal to be delivered to the old group-leader task, which does not exist.

Mitigation
Install update from vendor's repository.

Vulnerable software versions

Linux kernel: All versions
