CVE-2026-68327

Published Aug 10, 2026 EPSS 0.18% (7th pctl)

Overview

CVE-2026-68327 is a known-severity vulnerability. It was published on August 10, 2026.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
