{"id":"CVE-2026-68133","summary":"ice: fix PTP Call Trace during PTP release","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nice: fix PTP Call Trace during PTP release\n\nIf a PF reset occurs when the PTP state is ICE_PTP_UNINIT, then\nice_ptp_rebuild() will update the state to ICE_PTP_ERROR. 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.","modified":"2026-08-18T03:30:59.766080553Z","published":"2026-08-10T11:58:56.223Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68133.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/14fceda28069fdbe1bb49cdb6e1774892b583348"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7d517b255f669cedd09830214d55f2f413b34481"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e4406cbdd915f702d2ed9ee8b30683a16b06c6ac"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f6a7e00b81e35ef1325234925f2fe1e53b466f92"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68133.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68133"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"8293e4cb2ff54b1ec4f7206dcb74c908f62a3fb8"},{"fixed":"7d517b255f669cedd09830214d55f2f413b34481"},{"fixed":"e4406cbdd915f702d2ed9ee8b30683a16b06c6ac"},{"fixed":"14fceda28069fdbe1bb49cdb6e1774892b583348"},{"fixed":"f6a7e00b81e35ef1325234925f2fe1e53b466f92"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-68133.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.9.0"},{"fixed":"6.12.101"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.42"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-68133.json"}}],"schema_version":"1.9.0"}
