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

i2c: piix4: Fix a memory leak in the EFCH MMIO support

The recently added support for EFCH MMIO regions introduced a memory leak in that code path. The leak is caused by the fact that releaseresource() merely removes the resource from the tree but does not free its memory. We need to call releasemem_region() instead, which does free the memory. As a nice side effect, this brings back some symmetry between the legacy and MMIO paths.
