CVE-2026-68195

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: mt76: mt7615: drop TXRX_NOTIFY on non-mmio buses<br /> <br /> PKT_TYPE_TXRX_NOTIFY is an mmio-only event, but mt7615_rx_check() and<br /> mt7615_queue_rx_skb() dispatch it to mt7615_mac_tx_free() on every bus.<br /> mt7615_mac_tx_free() cleans the DMA tx queues with<br /> mt76_queue_tx_cleanup(), which calls queue_ops-&gt;tx_cleanup(). Only the<br /> mmio queue ops implement that callback; on the mt7663 USB and SDIO<br /> buses it is NULL, so a TXRX_NOTIFY there calls a NULL pointer in the RX<br /> worker. Same defect as the mt7921 and mt7925 patches in this series.<br /> <br /> Drop the event on non-mmio buses via mt76_is_mmio(), as in<br /> commit 5683e1488aa9 ("wifi: mt76: connac: do not check WED status for<br /> non-mmio devices").
