In the Linux kernel, the following vulnerability has been resolved: ice: fix PTP Call Trace during PTP release If a PF reset occurs when the PTP state is ICE_PTP_UNINIT, then ice_ptp_rebuild() will update the state to ICE_PTP_ERROR. 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.
