CVE-2026-90354

/// Technical description

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

wifi: mt76: mt7915: fix double hif2 init on the non-WED path

mt7915_pci_init_hif2() was called unconditionally and again inside the

WED-inactive branch. The helper increments the global hif_idx, writes the

PCIe RECOG_ID register and takes a get_device() reference via

mt7915_pci_get_hif2(), while removal only drops one reference. On non-WED

dual-hif hardware this double-incremented hif_idx, wrote RECOG_ID twice and

leaked a device reference. Only the call inside the WED-inactive branch is

correct; drop the unconditional one. hif2 is already initialised to NULL.

/// 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.
