Use After Free in Linux kernel - CVE-2026-23273

Published: March 20, 2026


Vulnerability identifier: #VU124177
CSH Severity: Low
CVSS v4: 6.8 [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]
CVE-ID: CVE-2026-23273
CWE-ID: CWE-416
Exploitation vector: Local access
Exploit availability: No public exploit available

Vulnerability details

The vulnerability allows a local attacker to cause a denial of service.

The vulnerability exists due to a use-after-free in the macvlan component of the Linux kernel when handling network interface creation errors. A local attacker can send a specially crafted netlink message to trigger improper RCU grace period handling during macvlan device creation, leading to a use-after-free condition.

Exploitation does not require elevated privileges and can result in a system crash due to access of already freed memory in the kernel network stack.
