About this tag
The ath6kl driver tag covers Linux kernel security issues affecting the older Qualcomm Atheros AR600x Wi-Fi hardware supported by this driver. Recent coverage examines out-of-bounds memory-access and firmware-event buffer flaws identified as CVE-2026-68199, CVE-2026-68352, and CVE-2026-68353. These issues matter primarily on Linux systems, embedded and industrial devices, Android-derived builds, or dual-boot and virtualized environments that actually load the ath6kl module. Articles track fixes backported to Linux 6.6.148, 6.12.101, 6.18.42, and 7.1.6, along with Linux 7.2-rc5. Windows itself and ordinary modern Qualcomm Wi-Fi adapters are not affected by these Linux driver flaws.

    CVE-2026-68353: Windows Unaffected by Linux ath6kl Wi-Fi Flaw

    CVE-2026-68353 fixes an out-of-bounds read in Linux’s Qualcomm Atheros ath6kl Wi‑Fi driver, but the immediate action is narrower than the new CVE entry may suggest: Windows itself is not affected by this Linux kernel driver flaw. The exposure is relevant to Linux installations, embedded devices...
