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.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/14fceda28069fdbe1bb49cdb6e1774892b583348","https://git.kernel.org/stable/c/7d517b255f669cedd09830214d55f2f413b34481","https://git.kernel.org/stable/c/e4406cbdd915f702d2ed9ee8b30683a16b06c6ac","https://git.kernel.org/stable/c/f6a7e00b81e35ef1325234925f2fe1e53b466f92"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:54.990491175+00:00"},"epss":{"cve":"CVE-2026-68133","score":0.00175,"percentile":0.07021,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
