Official 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.

Technical Analysis

CVE-2026-31511 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.
