Linux Kernel HID Corsair Void Power Supply Value Update Vulnerability Leading to Kernel Panic

A vulnerability in the Linux kernel's handling of HID Corsair Void devices can cause a kernel panic. The issue arises because the 'corsair_void_process_receiver' function can be called from an interrupt context, and locking the 'battery_mutex' within it was leading to a panic. This vulnerability has been addressed by moving the critical section into a separate work handler, which is shared with 'battery_add_work' and 'battery_remove_work', eliminating the need for locking.

Impact

The vulnerability could lead to a kernel panic, causing a denial of service by crashing the system.
