Overview

CVE-2026-23151 is a medium-severity vulnerability. It was published on February 14, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. 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 memory leak in set_ssp_complete

Fix memory leak in set_ssp_complete() where mgmt_pending_cmd structures

are not freed after being removed from the pending list.

Commit 302a1f674c00 ("Bluetooth: MGMT: Fix possible UAFs") replaced

mgmt_pending_foreach() calls with individual command handling but missed

adding mgmt_pending_free() calls in both error and success paths of

set_ssp_complete(). Other completion functions like set_le_complete()

were fixed correctly in the same commit.

This causes a memory leak of the mgmt_pending_cmd structure and its

associated parameter data for each SSP command that completes.

Add the missing mgmt_pending_free(cmd) calls in both code paths to fix

the memory leak. Also fix the same issue in set_advertising_complete().

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.
