"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: sparx5: skip ptp deinit if init was skipped\n\nsparx5_ptp_init() returns early on the base lan969x variants\nbecause they do not have the SPX5_FEATURE_PTP flag. It also returns early\nwhen no \"ptp\" interrupt is described. Unbinding the driver then causes a\nNULL pointer dereference when cleaning up uninitialized tx_skbs queues:\n\n Unable to handle kernel NULL pointer dereference at virtual address\n 0000000000000008\n Call trace:\n skb_queue_purge_reason+0x68/0x120 (P)\n sparx5_ptp_deinit+0x64/0xc0\n mchp_sparx5_remove+0x38/0x70\n platform_remove+0x20/0x30\n device_remove+0x4c/0x80\n\nBefore per-port tx_skbs were added, a NULL dereference would have happened\nwhen calling ptp_clock_unregister() on the never-registered PTP clocks.\n\nFix by returning early in sparx5_ptp_deinit() if PTP is not used."
