Vulnerability from github – Published: 2025-04-01 18:30 – Updated: 2025-10-30 21:30

Details

In the Linux kernel, the following vulnerability has been resolved:

HID: corsair-void: Update power supply values with a unified work handler

corsair_void_process_receiver can be called from an interrupt context, locking battery_mutex in it was causing a kernel panic. Fix it by moving the critical section into its own work, sharing this work with battery_add_work and battery_remove_work to remove the need for any locking

Severity ?

5.5 (Medium)
