Overview

CVE-2026-64011 is a high-severity vulnerability. It was published on July 19, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

nfc: llcp: Fix use-after-free in llcp_sock_release()

llcp_sock_release() unconditionally unlinks the socket from the local

sockets list. However, if the socket is still in connecting state, it

is on the connecting list.

Fix this by checking the socket state and unlinking from the correct list.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
