Improper locking in Linux kernel - CVE-2024-26740

Published: June 3, 2024 / Updated: May 14, 2025


Vulnerability identifier: #VU90789
CSH Severity: Low
CVSS v4 BT: 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]
CVE-ID: CVE-2024-26740
CWE-ID: CWE-667
Exploitation vector: Local access
Exploit availability: No public exploit available

Vulnerability details

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

The vulnerability exists due to improper locking within the mirred_egress_to_ingress_tcp_test() function in tools/testing/selftests/net/forwarding/tc_actions.sh, within the is_mirred_nested() and tcf_mirred_to_dev() functions in net/sched/act_mirred.c. A local user can perform a denial of service (DoS) attack.
