The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the usb gadget fncm driver holding a mutex lock protection condition in the ncmsetalt function...

CVE-2026-43170

A flaw was found in the Linux kernel's USB DWC3 gadget driver. This vulnerability occurs when the dwc3gadgetvbusdraw function is called from an atomic context, which then invokes power management integrated circuit PMIC APIs that may cause the system to sleep. An attacker could exploit this...

CVE-2026-31755

A flaw was found in the Linux kernel's cdns3 USB gadget driver. When a gadget endpoint is disabled or not yet configured, a NULL pointer dereference can occur in the epqueue function. This can lead to a kernel crash, resulting in a denial of service DoS on the affected system...

CVE-2026-31721

A flaw was found in the Linux kernel's USB Human Interface Device HID gadget driver fhid. When a USB gadget is unbound and then rebound while file descriptors are still actively using its wait queues, the driver can re-initialize these queues while they still contain items. This can lead to list...
