cfg80211

CVE-2026-31548 is the kind of Linux kernel flaw that looks narrow at first glance but carries broad operational meaning for anyone managing Wi-Fi-enabled Linux systems, embedded devices, lab workstations, or Linux workloads tied into Windows-heavy environments. The bug sits in cfg80211, the...

The Linux kernel’s CVE-2026-23336 is a classic example of a small-looking race condition with outsized consequences: a use-after-free in the Wi-Fi configuration stack, specifically around cfg80211 and rfkill_block work. The upstream fix is straightforward in concept—cancel the pending work...

A subtle race in the Linux wireless stack — tracked as CVE-2025-21979 — can let a queued wiphy work item run after its owning wiphy object has already been freed, producing a classic use-after-free that reliably threatens system availability and, in worst cases, integrity; the Linux kernel...

The Linux kernel patch for CVE-2025-37973 fixes a bounds-calculation error in the wifi subsystem’s cfg80211 code that could produce an out‑of‑bounds access during multi‑link element defragmentation — and Microsoft’s public advisory names Azure Linux as the Microsoft product the company has...

Microsoft’s brief advisory that “Azure Linux includes this open‑source library and is therefore potentially affected” is accurate as a product‑scoped attestation, but it is not a categorical proof that no other Microsoft product carries the same vulnerable Linux kernel component — any Microsoft...

CVE-2025-38643 is a recently disclosed Linux kernel vulnerability in the wireless subsystem — a missing lock in cfg80211_check_and_end_cac — and while Microsoft’s advisory names Azure Linux explicitly, that does not mean Azure Linux is the only Microsoft product that could include the affected...
