In the Linux kernel, the following vulnerability has been resolved: watchdog: sp5100_tco: 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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
