This will result in the following PTP release call trace during driver unload: kernel BUG at lib/list_debug.c:52! ice_ptp_release+0x332/0x3c0 [ice] ice_deinit_features.part.0+0x10e/0x120 [ice] ice_remove+0x100/0x220 [ice] This was observed when passing PF1 through to a VM. ice_ptp_init() fails because ctrl_pf is NULL and sets the state to ICE_PTP_UNINIT. Fix by detecting the ICE_PTP_UNINIT state in ice_ptp_rebuild() and returning without error, preventing the invalid state transition to ICE_PTP_ERROR. The only valid path to ICE_PTP_ERROR is from ICE_PTP_RESETTING after a failed rebuild. The Linux kernel CVE team has assigned CVE-2026-68133 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/net/ethernet/intel/ice/ice_ptp.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/7d517b255f669cedd09830214d55f2f413b34481 https://git.kernel.org/stable/c/e4406cbdd915f702d2ed9ee8b30683a16b06c6ac https://git.kernel.org/stable/c/14fceda28069fdbe1bb49cdb6e1774892b583348 https://git.kernel.org/stable/c/f6a7e00b81e35ef1325234925f2fe1e53b466f92
