About this tag
The wi-fi security tag on WindowsForum.com covers recent Linux kernel Wi-Fi driver and wireless-stack vulnerabilities, including CVE-2026-68199, CVE-2026-68326, CVE-2026-68406, CVE-2026-68408, CVE-2026-68404, CVE-2026-68414, CVE-2026-68405, and CVE-2026-68353. These threads detail memory-safety flaws, races, deadlocks, and validation gaps in components like ath6kl, mwifiex, cfg80211, and mac80211, with fixes in specific stable kernel versions. A recurring theme is clarifying that these Linux-specific issues do not affect Windows itself, but may impact dual-boot, virtualized, or embedded environments. The content emphasizes practical patching steps, kernel backport status, and the absence of CVSS scores or exploitation reports for several records.

    CVE-2026-68405: Linux AP VLAN Kernel Fix Reaches Stable

    Linux kernel maintainers have assigned CVE-2026-68405 to a mac80211 locking flaw that can trigger a kernel warning when an AP VLAN interface is being stopped while buffered multicast traffic with transmit-status handling is still present. The upstream fix is already in the stable kernel trees...

    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...

    CVE-2026-68407 Causes Linux Wi-Fi AP Memory Leak

    CVE-2026-68407 fixes a small but real kernel-memory leak in Linux Wi‑Fi access-point configuration: a malformed Enhanced Multiple BSSID Advertisement request can cause nl80211 to allocate Reduced Neighbor Report data, reject the request, and fail to release that allocation. For most Windows...
