ath12k driver

About this tag
The ath12k driver is the Linux kernel driver for Qualcomm Atheros Wi-Fi chipsets, including Wi-Fi 7 hardware such as QCN9274 and WCN7850. Recent discussions on WindowsForum.com cover multiple CVEs affecting this driver, including memory leaks, buffer overflows, and crash bugs in the RX error path and monitor path processing. Microsoft's Azure Linux distribution has been publicly attested as potentially affected by several of these vulnerabilities, though the absence of attestation for other Microsoft products does not guarantee they are unaffected. Security teams should apply upstream kernel patches and verify their specific artifacts.
