CVE-2026-64143

Estado: AnalizadaMedia (5.5)—

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

platform/x86: uniwill-laptop: Do not enable the charging limit even when forced

It seems that on some older models (~2020) the battery charging limit can permanently damage the battery. Prevent users from enabling this feature thru the "force" module parameter to avoid causing permanent hardware damage on such devices.
