NULL pointer dereference in Linux kernel - CVE-2026-23398

Published: March 26, 2026


Vulnerability identifier: #VU124642
CSH Severity: Medium
CVSS v4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
CVE-ID: CVE-2026-23398
CWE-ID: CWE-476
Exploitation vector: Remote access
Exploit availability: No public exploit available

Vulnerability details

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

The vulnerability exists due to a NULL pointer dereference in the icmp_tag_validation function when handling ICMP Fragmentation Needed error messages with a quoted inner IP header containing an unregistered protocol number. A remote attacker can send a specially crafted ICMP packet to cause a kernel panic in softirq context.

Exploitation requires the target system to have ip_no_pmtu_disc set to 3 (hardened PMTU mode).
