About this tag
The iwlwifi tag on WindowsForum.com covers discussions about the Linux iwlwifi driver for Intel wireless hardware, particularly recent security vulnerabilities such as CVE-2025-38656 and CVE-2025-38096. Topics include kernel-level use-after-free bugs, denial-of-service risks, and the impact on Azure Linux and other Microsoft products. The content focuses on patching strategies, product-scoped risk assessments, and the importance of updating iwlwifi in multi-tenant and cloud environments. While the tag is Linux-specific, it is relevant to Windows users who run Linux subsystems or virtual machines on Windows, as well as IT professionals managing hybrid infrastructure.
