CVE-2026-23151

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().
