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-...

CVE-2026-68194

The CVE-2026-68194 issue affects Linux kernel wifi driver stack mt76/mt7921: TXRX_NOTIFY is an mmio-only event but was dispatched on non-mmio buses (USB/SDIO) via mt7921_rx_check()/mt7921_queue_rx_skb(), causing a NULL pointer dereference in mt7921_mac_tx_free() when mt76_queue_tx_cleanup() calls...

CVE-2026-68193

The CVE-2026-68193 entry concerns the Linux kernel’s wifi mt76 mt7925 driver. A TXRX_NOTIFY event is mmio-only, but mt7925_rx_check() and mt7925_queue_rx_skb() dispatched it to mt7925_mac_tx_free() on non-mmio buses, where tx cleanup called a NULL queue_ops->tx_cleanup() on USB. This caused a ...

EUVD-2026-55277

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix mmiotrace possible NULL dereferencing of hiter-dev If the mmiopipeopen fails to find a PCI device, the hiter-dev will be assigned to NULL. The mmiotrace read function dereferences the hiter-dev if hiter exists. Chang...

CVE-2026-68176

The CVE-2026-68176 entry concerns the Linux kernel tracing subsystem (mmiotrace) where a NULL dereference could occur if mmio_pipe_open() fails to locate a PCI device and hiter->dev is NULL. The read() path previously dereferenced hiter->dev without verifying it; the fix adds a check for hi...

CVE-2026-68175

The CVE-2026-68175 entry documents a fixed resource leak in the Linux kernel tracing subsystem (mmiotrace) related to trace_pipe close. Specifically, mmio_pipe_open() allocated a header_iter and took a pci_dev reference when trace_pipe opened; mmio_close() frees them but was not wired to the trac...
