CVE-2026-64337

A flaw was found in the Linux kernel's USB mtu3 gadget driver. When the mtu3gadgetqueue function encounters a failure during the preparation of a USB transfer, the associated Direct Memory Access DMA mapping is not properly released. This leaves the DMA mapping active, which can lead to a resourc...

CVE-2026-64337

CVE-2026-64337 (Linux kernel): usb mtu3 flaw where mtu3_gadget_queue() maps the request before verifying QMU GPD space, causing a DMA mapping to remain active if mtu3_prepare_transfer() fails and the request isn’t linked. The fix unmaps the DMA on the failed queue path before returning. Documents...

CVE-2026-31741

A flaw was found in the Linux kernel's rz-mtu3-cnt counter module. A local user can exploit this by repeatedly writing '0' to the sysfs enable file, which causes the runtime Power Management PM usage count to underflow. This can lead to attempts to access hardware registers with their clocks off,...

CVE-2026-31740

A flaw was found in the Linux kernel's rz-mtu3-cnt counter driver. A race condition exists where multiple sub-drivers can simultaneously attempt to assign their device pointers to a shared channel member. This can result in the counter sub-driver performing power management actions on an unintend...
