This resolves a deadlock scenario where\nucsi_displayport_remove_partner holds con->mutex waiting for\ndp_altmode_work to complete while dp_altmode_work attempts to acquire it.\n\n## Affected\n\n- `Linux >= af8622f6a585d8d82b11cd7987e082861fd0edd3 < f4bd982563c2fd41ec9ca6c517c392d759db801c`\n- `Linux >= af8622f6a585d8d82b11cd7987e082861fd0edd3 < f32451ca4cb7dc53f2a0e2e66b84d34162747eb7`\n- `Linux >= af8622f6a585d8d82b11cd7987e082861fd0edd3 < 962ce9028ca6eb450d5c205238a3ee27de9d214d`\n- `Linux >= af8622f6a585d8d82b11cd7987e082861fd0edd3 < 5924b324468845fc795bd76f588f51d7ab4f202d`\n- `Linux >= af8622f6a585d8d82b11cd7987e082861fd0edd3 < 61fc1a8e1e10cc784cab5829930838aaf1d37af5`\n- `Linux >= af8622f6a585d8d82b11cd7987e082861fd0edd3 < 364618c89d4c57c85e5fc51a2446cd939bf57802`\n- `Linux 5.2`\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":[]}
