This covers both the HCD initialization error path\nand normal HCD removal.\n\n## Affected\n\n- `Linux >= 7359d482eb4d3967cc8be354405ae6be6eaf732c < 441be312fce927443eae2821f502344d953c38bb`\n- `Linux >= 7359d482eb4d3967cc8be354405ae6be6eaf732c < 4333174ea52c863a50bb3e0a4726bf9f7cdf7524`\n- `Linux >= 7359d482eb4d3967cc8be354405ae6be6eaf732c < 79ba37dd38a321cb32a79332a3e3c68dd334dca9`\n- `Linux >= 7359d482eb4d3967cc8be354405ae6be6eaf732c < fd772af9512cdecb83de34a461801533828e77fd`\n- `Linux 3.10`\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":[]}
