CVE-2026-80934

A flaw was found in the Linux kernel's mt76: mt7996 Wi-Fi driver. The driver incorrectly manages Direct Memory Access DMA mappings when processing AddBA request frames, causing a continuous leak of these mappings. Over time, this resource exhaustion can lead to a Denial of Service DoS for the Wi-...

CVE-2026-80934

CVE-2026-80934 affects the Linux kernel WiFi driver mt76 mt7996 (and mt7992). The root cause is a TX DMA mapping leak on AddBA request action frames: these frames use a HW MAC-TXP layout, but the TX-free path incorrectly decodes them as FW-TXP, causing the unmap loop to run zero times and the DMA...
