If get_1284_register()\nfails, the error path drops the driver private data and the USB device\nreference, but leaves the parport device registered.\n\nLeaving the port registered is more than a private allocation leak:\nparport_register_port() has already reserved a parport number and\nregistered the parport bus device, while pp->private_data still points at\nthe private data that the common error path is about to release.\n\nUndo the pre-announce registration in the get_1284_register() failure\nbranch before jumping to the common private-data cleanup path. Clear\npriv->pp first, matching the disconnect path and avoiding a stale pointer\nin the private data.\n\nThis issue was identified during our ongoing static-analysis research while\nreviewing kernel code.\n\n## Affected\n\n- `Linux >= 04736c1bc32197f7d859e01a96ae80a16659931d < 6bbb98bec71b577fda4f4b48f7aea5874b04a576`\n- `Linux >= 4eaf2331a77996bbbaf2b824d452ac8ebda7e6e7 < 93563243377f8e9b46cc94d9c4f06533dd31b141`\n- `Linux >= 8fc246a8a456679993df565d3c9e3da28030ee43 < 1712fd71a5aaf81e47c747f180535fa963ad7830`\n- `Linux >= 10132ccf99f49b43aeb7470df50d72344a601ad6 < 0b3073f40cc9f95d5ff0037eb0a06f5c1725a7ea`\n- `Linux >= 3295f1b866bfbcabd625511968e8a5c541f9ab32 < 5e62d7857fd51b908b8371062ee839739a086bbe`\n- `Linux >= 3295f1b866bfbcabd625511968e8a5c541f9ab32 < 729b68a5bad71220ae0914c8bdab9488ad5be6c8`\n- `Linux >= 3295f1b866bfbcabd625511968e8a5c541f9ab32 < 48dd0b2ec9f2e97c486eb68cd0a64b25c1c3df3e`\n- `Linux >= 3295f1b866bfbcabd625511968e8a5c541f9ab32 < b4ecbdc4f8830f5586c4a5cfc384c00f20f8f8b3`\n- `Linux 02d13616ca30014ed96302e51a5b0e17664e58bc`\n- `Linux dff3b01e91a3df93063b03d0f8dd5c40546687ec`\n- `Linux 489d77fbd66375972a380d207f7eb39b00c4a67b`\n- `Linux >= 5.10.221 < 5.10.261`\n- `Linux >= 5.15.162 < 5.15.212`\n- `Linux >= 6.1.96 < 6.1.178`\n- `Linux >= 6.6.36 < 6.6.145`\n- `Linux >= 4.19.317 < 4.20`\n- `Linux >= 5.4.279 < 5.5`\n- `Linux >= 6.9.7 < 6.10`\n- `Linux 6.10`\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":[]}
