This will\nresult in the following PTP release call trace during driver unload:\n\n    kernel BUG at lib/list_debug.c:52!\n    ice_ptp_release+0x332/0x3c0 [ice]\n    ice_deinit_features.part.0+0x10e/0x120 [ice]\n    ice_remove+0x100/0x220 [ice]\n\nThis was observed when passing PF1 through to a VM. ice_ptp_init()\nfails because ctrl_pf is NULL and sets the state to ICE_PTP_UNINIT.\n\nFix by detecting the ICE_PTP_UNINIT state in ice_ptp_rebuild() and\nreturning without error, preventing the invalid state transition to\nICE_PTP_ERROR. The only valid path to ICE_PTP_ERROR is from\nICE_PTP_RESETTING after a failed rebuild.","published":"2026-08-10T13:19:59.000Z","lastModified":"2026-08-17T05:18:13.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00175,"percentile":0.06996,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"unknown","text":"Not yet scored.
