      "title": "bnxt_en: Fix NULL pointer crash in bnxt_ptp_enable during error cleanup",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nbnxt_en: Fix NULL pointer crash in bnxt_ptp_enable during error cleanup\n\nWhen bnxt_init_one() fails during initialization (e.g.,\nbnxt_init_int_mode returns -ENODEV), the error path calls\nbnxt_free_hwrm_resources() which destroys the DMA pool and sets\nbp->hwrm_dma_pool to NULL. Subsequently, bnxt_ptp_clear() is called,\nwhich invokes ptp_clock_unregister().\n\nSince commit a60fc3294a37 (\"ptp: rework ptp_clock_unregister() to\ndisable events\"), ptp_clock_unregister() now calls\nptp_disable_all_events(), which in turn invokes the driver's .enable()\ncallback (bnxt_ptp_enable()) to disable PTP events before completing the\nunregistration.\n\nbnxt_ptp_enable() attempts to send HWRM commands via bnxt_ptp_cfg_pin()\nand bnxt_ptp_cfg_event(), both of which call hwrm_req_init(). This\nfunction tries to allocate from bp->hwrm_dma_pool, causing a NULL\npointer dereference:\n\n  bnxt_en 0000:01:00.0 (unnamed net_device) (uninitialized): bnxt_init_int_mode err: ffffffed\n  KASAN: null-ptr-deref in range [0x0000000000000028-0x000000000000002f]\n  Call Trace:\n   __hwrm_req_init (drivers/net/ethernet/broadcom/bnxt/bnxt_hwrm.c:72)\n   bnxt_ptp_enable (drivers/net/ethernet/broadcom/bnxt/bnxt_ptp.c:323 drivers/net/ethernet/broadcom/bnxt/bnxt_ptp.c:517)\n   ptp_disable_all_events (drivers/ptp/ptp_chardev.c:66)\n   ptp_clock_unregister (drivers/ptp/ptp_clock.c:518)\n   bnxt_ptp_clear (drivers/net/ethernet/broadcom/bnxt/bnxt_ptp.c:1134)\n   bnxt_init_one (drivers/net/ethernet/broadcom/bnxt/bnxt.c:16889)\n\nLines are against commit f8f9c1f4d0c7 (\"Linux 6.19-rc3\")\n\nFix this by clearing and unregistering ptp (bnxt_ptp_clear()) before\nfreeing HWRM resources.",
