CVE-2026-68199

CVE-2026-68199 concerns a flaw in the Linux kernel’s ath6kl Wi‑Fi driver where the firmware-provided ADDBA window size (win_sz) can be out of range. The out-of-range value is logged but not rejected, causing TID_WINDOW_SZ() to allocate kzalloc memory based on an invalid size, leading to zero-size...

CVE-2026-68195 wifi: mt76: mt7615: drop TXRX_NOTIFY on non-mmio buses

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7615: drop TXRXNOTIFY on non-mmio buses PKTTYPETXRXNOTIFY is an mmio-only event, but mt7615rxcheck and mt7615queuerxskb dispatch it to mt7615mactxfree on every bus. mt7615mactxfree cleans the DMA tx queues with...

CVE-2026-68195

The CVE describes a Linux kernel issue in the mt76/mt7615 wireless driver where PKT_TYPE_TXRX_NOTIFY is mmio-only but was dispatched on non-mmio buses, causing a NULL dereference when mt7615_mac_tx_free() calls tx_cleanup() with a NULL queue_ops->tx_cleanup(). The fix drops TXRX_NOTIFY on non-...
