For example if user unloads the\ndriver while at the same time plugging  a device router we may have\nscheduled tb_handle_hotplug() to run. Avoid possible UAF in this case by\ntaking the domain reference before scheduling the hotplug handler in\ntb_queue_hotplug().\n\n## Affected\n\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 06b2e894e640f6a3dbeb536a2d26d72426b26a46`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 1d991f749a8255ee2ecc6307e2f27354ab631827`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < e8656465d08ed832e120c9cca4a6d0c8ccb45698`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < b61a4ae2ec6a0d363615d01106e0a2d284133a38`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 04df2985159e381c88a923fae1bec2f8d0272412`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 0a87af3b1e3aa2e09d160848daf0c39e765b73de`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 138ec65b2c761f065b19d115aed2b8246fc272f5`\n- `Linux < 5.10.271`\n- `Linux < 5.15.222`\n- `Linux < 6.1.189`\n- `Linux < 6.6.158`\n- `Linux < 6.12.111`\n- `Linux < 6.18.53`\n- `Linux (all versions)`\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":[]}
