Technical description

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

release_resource() merely removes the resource from the tree but does

not free its memory. We need to call release_mem_region() instead,

which does free the memory. As a nice side effect, this brings back

some symmetry between the legacy and MMIO paths.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
