Battery Charging Limitation Issue in Uniwill Laptop by Linux

CVE-2026-64143

What is CVE-2026-64143?

The Linux kernel has identified a significant issue affecting Uniwill laptops, specifically related to the battery charging limit feature. On certain older models from around 2020, enabling this feature could potentially lead to permanent damage to the battery. To mitigate this risk, the system has been updated to prevent users from forcing the enabling of the charging limit via the 'force' module parameter. This modification is essential to protect users from unintended hardware failures and ensure optimal battery performance.
