CVE-2026-64583

Summary: CVE-2026-64583 affects the Linux kernel usb gadget Broadcom BDC UDC driver. The issue arises from the irq handling window after devm_request_irq() but before teardown, allowing a shared IRQ to dereference freed memory and cause NULL-deref or use-after-free in bdc_udc_interrupt and relate...

CVE-2026-64331

A flaw was found in the Linux kernel's usbip virtual USB device controller vudc. This vulnerability, a NULL pointer dereference, occurs when vepallocrequest fails to initialize a vrequest's udc field, causing asynchronous input/output AIO cancellations on the FunctionFS path to arrive without a...

SUSE CVE-2026-64346

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: udc: Fix use-after-free in gadgetmatchdriver The udc structure acts as the management structure for the gadget, but their lifecycles are decoupled. A race condition exists where usbdelgadget frees the udc memory e.g....

CVE-2026-64331 usbip: vudc: fix NULL deref in vep_dequeue()

In the Linux kernel, the following vulnerability has been resolved: usbip: vudc: fix NULL deref in vepdequeue vepallocrequest wasn't initializing vrequest-udc, so cancellations on the FunctionFS AIO path were arriving in vepdequeue without a valid UDC reference. Since vrequest-udc is never actual...

CVE-2026-10668 Host-triggerable control-endpoint wedge (DoS) in Nuvoton NuMaker HSUSBD UDC driver

The Nuvoton NuMaker HSUSBD USB device-controller driver drivers/usb/udc/udcnumaker.c armed the control Data IN stage unconditionally base-CEPTXCNT = len in numakerhsusbdeptrigger. Because the HSUSBD hardware cannot disarm a control Data IN already armed for a previous transfer, a USB host that...
