Vulnerability identifier: #VU95651

Vulnerability risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The ELF loader in Linux kernel 2.4 before 2.4.25 allows local users to cause a denial of service (crash) via a crafted ELF file with an interpreter with an invalid arch (architecture), which triggers a BUG() when an invalid VMA is unmapped.

Mitigation
Install update from vendor's repository.
