Linux Kernel Wireless IBSS Channel Scanning Issue

CVE-2026-98425

What is CVE-2026-98425?

In the Linux kernel, a notable vulnerability has been identified relating to the handling of Independent Basic Service Set (IBSS) networks. The function ieee80211_request_ibss_scan() previously issued warnings when the regulatory domain left no allowed channels for scanning. This scenario can occur if the regulatory domain changes dynamically while the IBSS is active. Subsequently, the function has been updated to avoid unnecessary warnings during the brief grace period of operation, thus ensuring smoother performance in wireless networking without alerts that could confuse users.
