In the Linux kernel, the following vulnerability has been resolved:
ice: Fix PTP NULL pointer dereference during VSI rebuild
Fix race condition where PTP periodic work runs while VSI is being rebuilt, accessing NULL vsi->rx_rings.
The sequence was: 1. ice_ptp_prepare_for_reset() cancels PTP work 2. ice_ptp_rebuild() immediately queues PTP work 3. VSI rebuild happens AFTER ice_ptp_rebuild() 4. PTP work runs and accesses NULL vsi->rx_rings
Fix: Keep PTP work cancelled during rebuild, only queue it after VSI rebuild completes in ice_rebuild().
Added ice_ptp_queue_work() helper function to encapsulate the logic for queuing PTP work, ensuring it's only queued when PTP is supported and the state is ICE_PTP_READY.
