CVE-2026-64454

CVE-2026-64454 affects the Linux kernel USB subsystem (dwc3) where gadget disconnect could run with IRQs disabled during suspend, triggering Lockdep warnings. Root cause: dwc3_gadget_suspend() holds dwc->lock with IRQs disabled and calls dwc3_disconnect_gadget(), causing gadget_driver->disc...

CVE-2026-64454

In the Linux kernel, the following vulnerability has been resolved: usb: dwc3: run gadget disconnect from sleepable suspend context dwc3gadgetsuspend takes dwc-lock with IRQs disabled and then calls dwc3disconnectgadget. For async callbacks that helper only uses plain spinunlock/spinlock, so the...

CVE-2026-64453

In the Linux kernel, the following vulnerability has been resolved: usb: misc: usbio: fix disconnect UAF in client teardown usbiodisconnect walks usbio-clilist in reverse and uninitializes each auxiliary device. auxiliarydeviceuninit drops the device reference, and for an unbound child that can r...

CVE-2026-64453

A use-after-free in the Linux kernel's usbio USB driver occurs during device disconnection. When usbio_disconnect() iterates the client list in reverse, auxiliary_device_uninit() can free the current struct usbio_client, causing the list_for_each_entry_reverse() iterator to dereference freed memo...

CVE-2026-64344

CVE-2026-64344 is a use-after-free in the Linux kernel's USB idmouse driver triggered by a disconnect race. The root cause is that mutex_unlock() is non-atomic and may still access the mutex structure after release, making it unsafe for managing object lifetime. The fix replaces direct mutex-base...

CVE-2026-64342

CVE-2026-64342 is a use-after-free vulnerability in the Linux kernel's iowarrior USB driver . Submitted write URBs are not stopped on close(), so they must be stopped unconditionally on disconnect() to prevent the completion handler from accessing freed memory. NVD scores it 7.8 HIGH (AV:L/AC:L/P...
