Vulnerability from fkie_nvd - Published: 2026-02-14 16:15 - Updated: 2026-03-17 21:11

5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Summary

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().
