Other completion functions like set_le_complete()\nwere fixed correctly in the same commit.\n\nThis causes a memory leak of the mgmt_pending_cmd structure and its\nassociated parameter data for each SSP command that completes.\n\nAdd the missing mgmt_pending_free(cmd) calls in both code paths to fix\nthe memory leak. Also fix the same issue in set_advertising_complete().\n\n## Affected\n\n- `Linux >= 0b60eb04b8524e1b4b3f07fea0d16fda9a677d9a < d7e42dc47beb48851bc0008c1e1b79126de9d975`\n- `Linux >= d71b98f253b079cbadc83266383f26fe7e9e103b < 1850a558d116d7e3e2ef36d06a56f59b640cc214`\n- `Linux >= 302a1f674c00dd5581ab8e493ef44767c5101aab < 3b6318505378828ee415d6ef678db6a74c077504`\n- `Linux >= 302a1f674c00dd5581ab8e493ef44767c5101aab < 1b9c17fd0a7fdcbe69ec5d6fe8e50bc5ed7f01f2`\n- `Linux 87a1f16f07c6c43771754075e08f45b41d237421`\n- `Linux >= 6.12.59 < 6.12.69`\n- `Linux >= 6.16.10 < 6.17`\n- `Linux 6.17`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
