Overview

CVE-2026-74412 is a high-severity vulnerability. It was published on August 15, 2026 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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

wifi: rtw88: fix wrong pci_get_drvdata type in AER handlers

rtw88 stores an ieee80211_hw pointer via pci_set_drvdata() at probe

time, but io_error_detected() and io_resume() retrieve it as a

net_device pointer. This causes netif_device_detach/attach to

operate on an ieee80211_hw struct, reading and writing at wrong

offsets.

Use ieee80211_stop_queues/wake_queues instead, consistent with

every other queue stop/start path in the driver.

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.
