CVE-2026-68327: In the Linux kernel, the following vulnerability has been resolved: wan: wanxl: Only reset hardware after BAR mapping
Summary
A bug in the Linux kernel's wanxl driver could crash the system during early initialization failures because the removal function tried to reset hardware before the memory mapping (BAR, or base address register, which tells the driver where hardware controls are located in memory) was set up, causing it to access a NULL pointer. The fix ensures the hardware reset only happens after the memory mapping is properly established.
Solution / Mitigation
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.
