wiphy

The wiphy tag on WindowsForum.com covers discussions about the Linux wireless configuration layer, particularly the wiphy (wireless PHY) object used in the cfg80211 subsystem. Content includes security vulnerabilities such as CVE-2025-21979, a use-after-free bug where a queued wiphy work item could run after its owning wiphy object was freed, threatening system availability and integrity. The Linux kernel community addressed this by canceling pending wiphy work before freeing the object, with major distributions releasing kernel updates. The tag focuses on Linux wireless stack internals, kernel patching, and related security advisories.
