About this tag
The wifi vulnerabilities tag covers recent Linux kernel security issues affecting wireless configuration and device drivers. Tagged discussions examine CVE-2026-68402, a cfg80211 parsing flaw that can cause a one-byte out-of-bounds read when a malicious access point sends malformed 802.11 management-frame data, and CVE-2026-68197, a Marvell mwifiex driver null-pointer dereference that can crash systems during TDLS peer-link setup. The coverage emphasizes practical patch management, upstream Linux wireless fixes, affected kernel components, and denial-of-service implications rather than broad claims of remote system takeover. It is useful for tracking technical advisories and the progress of fixes through the kernel development process.

    CVE-2026-68402: Patch Linux Wi-Fi Parser Overread

    Linux kernel users running Wi-Fi hardware should treat CVE-2026-68402 as a patch-management issue rather than evidence of a broad remote takeover bug. The flaw is in cfg80211, the kernel’s common Wi-Fi configuration and frame-parsing layer, and a malicious access point can trigger a one-byte...

    CVE-2026-68197: Upstream Fixes Marvell Wi-Fi TDLS Crash

    CVE-2026-68197 fixes a Linux kernel crash in the Marvell mwifiex Wi‑Fi driver, triggered when a device connected to an access point advertising HT capabilities but omitting the related HT Operation element attempts to establish a TDLS peer link. The flaw is a denial-of-service condition in...
