CWE ID 401
Summary
CVE-2022-49653: A memory leak vulnerability has been identified and addressed in the Linux kernel i2c driver's piix4 subsystem. The issue was introduced with the recent addition of EFCH MMIO (Memory-Mapped Input/Output) regions, where release_resource() only removed the resource from the tree without freeing the associated memory. To resolve this, release_mem_region() must be used instead to properly release the memory, bringing symmetry to both legacy and MMIO paths.
