Published Oct 7, 2025
·Updated
In the Linux kernel, the following vulnerability has been resolved:
platform/x86: mxm-wmi: fix memleak in mxmwmicallmxds|mx
The ACPI buffer memory (out.pointer) returned by wmievaluatemethod() is not freed after the call, so it leads to memory leak.
The method results in ACPI buffer is not used, so just pass NULL to wmievaluatemethod() which fixes the memory leak.
