CVE-2026-74413

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description In the rtw89 wifi driver, an issue exists in the Advanced Error Reporting (AER) handlers. The driver stores an ieee80211 hw pointer using pci set drvdata() during probe time, but the io error detected() and io resume() functions incorrectly retrieve this data as a net device pointer. This mismatch causes netif device detach() and netif device attach() to operate on an ieee80211 hw structure, leading to read and write operations at incorrect memory offsets.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
