CVE-2022-49653: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: from 5.15.42, before 5.15.54 (fixed in 5.15.54); from 5.17.10, before 5.18.11 (fixed in 5.18.11); version 5.19 only
