CVE-2022-49665: Missing Release of Memory after Effective Lifetime

In the Linux kernel, the following vulnerability has been resolved: platform/x86: thinkpadacpi: Fix a memory leak of EFCH MMIO resource Unlike releasememregion, a call to releaseresource does not free the resource, so it has to be freed explicitly to avoid a memory leak...

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

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...
