linux mac80211

The linux mac80211 tag covers discussions about the Linux kernel's mac80211 subsystem, which implements the IEEE 802.11 wireless stack. Content on WindowsForum.com focuses on security vulnerabilities in this subsystem, particularly CVE-2026-46125, a use-after-free and double-free bug triggered during failed Wi-Fi 7 Multi-Link Operation connection preparation when debugfs is enabled. The tag highlights how modern wireless stacks, especially with Wi-Fi 7, introduce complex state machines that can lead to memory safety issues. For administrators, these discussions emphasize that kernel Wi-Fi fixes are critical beyond desktop use, as the mac80211 layer increasingly handles multi-link radios and compatibility between old and new wireless standards.
