In the Linux kernel, the following vulnerability has been resolved: HID: usbhid: fix deadlock in hid_post_reset() You can build a USB device that includes a HID component and a storage or UAS component. The components can be reset only together. That means that hid_pre_reset() and hid_post_reset() are in the block IO error handling. Hence no memory allocation used in them may do block IO because the IO can deadlock on the mutex held while resetting a device and calling the interface drivers. Use GFP_NOIO for all allocations in them.

A flaw was found in the Linux kernel's USB Human Interface Device (HID) subsystem. This vulnerability occurs when a USB device, containing both HID and storage or Universal Attached SCSI (UAS) components, is reset. During the reset process, memory allocation operations within the `hid_post_reset()` function can attempt block input/output (I/O) while a mutex is held, leading to a deadlock. This can result in a Denial of Service (DoS) for the affected system.
