CVE-2026-98700

A flaw was found in the Linux kernel's mac80211 wireless subsystem. The transmission function for encapsulated Ethernet frames fails to set the operating frequency band from the channel context on non-Multi-Link Device (MLD) interfaces. A local user generating network traffic on an affected interface can trigger this flaw, causing the system to calculate transmission rates using an incorrect band. Consequently, this issue may result in transmission failures or degraded wireless network performance.
