Overview

CVE-2026-31511 is a high-severity vulnerability. It was published on April 22, 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:

Bluetooth: MGMT: Fix dangling pointer on mgmt_add_adv_patterns_monitor_complete

This fixes the condition checking so mgmt_pending_valid is executed

whenever status != -ECANCELED otherwise calling mgmt_pending_free(cmd)

would kfree(cmd) without unlinking it from the list first, leaving a

dangling pointer. Any subsequent list traversal (e.g.,

mgmt_pending_foreach during __mgmt_power_off, or another

mgmt_pending_valid call) would dereference freed memory.

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.
