CVE-2026-68327
Detail
Received This CVE record has recently been published to the CVE List and has been included within the NVD dataset.
Description
In the Linux kernel, the following vulnerability has been resolved:
wan: wanxl: Only reset hardware after BAR mapping
wanxl_pci_init_one() stores the freshly allocated card in driver data
before the PLX BAR is mapped. Several early probe failures then unwind
through wanxl_pci_remove_one(), including failure to allocate the coherent
status area or to restore the DMA mask.
wanxl_pci_remove_one() unconditionally calls wanxl_reset(), and
wanxl_reset() dereferences card->plx. On those early failures card->plx
is still NULL, so the error path can dereference a NULL MMIO pointer.
Only issue the hardware reset once the BAR mapping exists. The remaining
cleanup in wanxl_pci_remove_one() already checks whether later resources
were allocated.
This issue was found by a static analysis checker and confirmed by
manual source review.
