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 ICEPTPUNINIT, then iceptprebuild() will update the state to ICEPTPERROR. This will result in the following PTP release call trace during driver unload:

kernel BUG at lib/listdebug.c:52! iceptprelease+0x332/0x3c0 [ice] icedeinitfeatures.part.0+0x10e/0x120 [ice] iceremove+0x100/0x220 [ice]

This was observed when passing PF1 through to a VM. iceptpinit() fails because ctrlpf is NULL and sets the state to ICEPTPUNINIT.

Fix by detecting the ICEPTPUNINIT state in iceptprebuild() and returning without error, preventing the invalid state transition to ICEPTPERROR. The only valid path to ICEPTPERROR is from ICEPTPRESETTING after a failed rebuild.
