  "title": "net: sparx5: skip ptp deinit if init was skipped",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  net: sparx5: skip ptp deinit if init was skipped  sparx5_ptp_init() returns early on the base lan969x variants because they do not have the SPX5_FEATURE_PTP flag. It also returns early when no \u0022ptp\u0022 interrupt is described. Unbinding the driver then causes a NULL pointer dereference when cleaning up uninitialized tx_skbs queues:      Unable to handle kernel NULL pointer dereference at virtual address     0000000000000008     Call trace:     skb_queue_purge_reason\u002B0x68/0x120 (P)     sparx5_ptp_deinit\u002B0x64/0xc0     mchp_sparx5_remove\u002B0x38/0x70     platform_remove\u002B0x20/0x30     device_remove\u002B0x4c/0x80  Before per-port tx_skbs were added, a NULL dereference would have happened when calling ptp_clock_unregister() on the never-registered PTP clocks.  Fix by returning early in sparx5_ptp_deinit() if PTP is not used.",
