Description OSIDB Bzimport 2025-02-26 03:19:26 UTC 
In the Linux kernel, the following vulnerability has been resolved:

platform/x86: thinkpad_acpi: Fix a memory leak of EFCH MMIO resource

Unlike release_mem_region(), a call to release_resource() does not
free the resource, so it has to be freed explicitly to avoid a memory
leak.
