CVE-2026-64240

A flaw was found in the Linux kernel's igorplugusb driver. This vulnerability occurs because the driver incorrectly passes a pointer instead of the actual USB control request setup packet to the USB core. As a result, the USB core misinterprets the data, leading to an invalid request type and...

kernel: iommu/vt-d: Avoid NULL pointer dereference or refcount corruption

A flaw was found in the Linux kernel's Input-Output Memory Management Unit IOMMU virtualized direct memory access VT-d component. This vulnerability occurs when the system attempts to perform cleanup operations without a valid device identifier, leading to a null pointer dereference or incorrect...
