Out-of-bounds read in Linux kernel - CVE-2026-31405

Published: April 6, 2026


Vulnerability identifier: #VU124959
CSH Severity: High
CVSS v4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
CVE-ID: CVE-2026-31405
CWE-ID: CWE-125
Exploitation vector: Remote access
Exploit availability: No public exploit available

Vulnerability details

The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to an out-of-bounds read in handle_one_ule_extension() extension handler tables when processing network-controlled ULE extension header data. A remote attacker can send a specially crafted SNDU with an extension header type value of 255 to execute arbitrary code.

The out-of-bounds value may be dereferenced and called as a function pointer.
