| Subject: CVE-2025-21952: HID: corsair-void: Update power supply values with a unified work handler |
| |
| Description |
| =========== |
| |
| 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 |
| |
| The Linux kernel CVE team has assigned CVE-2025-21952 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
