  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwan: wanxl: Only reset hardware after BAR mapping\n\nwanxl_pci_init_one() stores the freshly allocated card in driver data\nbefore the PLX BAR is mapped.  Several early probe failures then unwind\nthrough wanxl_pci_remove_one(), including failure to allocate the coherent\nstatus area or to restore the DMA mask.\n\nwanxl_pci_remove_one() unconditionally calls wanxl_reset(), and\nwanxl_reset() dereferences card-\u003eplx.  On those early failures card-\u003eplx\nis still NULL, so the error path can dereference a NULL MMIO pointer.\n\nOnly issue the hardware reset once the BAR mapping exists.  The remaining\ncleanup in wanxl_pci_remove_one() already checks whether later resources\nwere allocated.\n\nThis issue was found by a static analysis checker and confirmed by\nmanual source review.",
