CVE-2026-90351

Summary

In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: mt7996: do not attach hif2 WED when the main WED attach failed

If the WED attach for the primary PCIe function fails, the probe path still attached wed_hif2 for the secondary function, leaving the device in an inconsistent half-WED configuration that crashes later. The hif2 call also re-enabled hwrro_mode, which the failed primary attach had just turned off.

Skip the hif2 WED setup when the primary WED device is not active.
