CVE-2022-48706

The CVE-2022-48706 entry concerns the Linux kernel and a memory-leak in the virtual data path (vdpa) IFCVF path. Root cause: ifcvf_mgmt_dev leaks memory if not freed on exit and the existing cleanup in ifcvf_init_hw does not handle it, so the fix adds proper cleanup at the return path to ensure m...
