CVE-2025-21952 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
