CVE-2026-68195

Published Aug 10, 2026 EPSS 0.21% (11th pctl)

Overview

CVE-2026-68195 is a known-severity vulnerability. It was published on August 10, 2026.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: mt7615: drop TXRX_NOTIFY on non-mmio buses

PKT_TYPE_TXRX_NOTIFY is an mmio-only event, but mt7615_rx_check() and

mt7615_queue_rx_skb() dispatch it to mt7615_mac_tx_free() on every bus.

mt7615_mac_tx_free() cleans the DMA tx queues with

mt76_queue_tx_cleanup(), which calls queue_ops->tx_cleanup(). Only the

mmio queue ops implement that callback; on the mt7663 USB and SDIO

buses it is NULL, so a TXRX_NOTIFY there calls a NULL pointer in the RX

worker. Same defect as the mt7921 and mt7925 patches in this series.

Drop the event on non-mmio buses via mt76_is_mmio(), as in

commit 5683e1488aa9 ("wifi: mt76: connac: do not check WED status for

non-mmio devices").

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
