However, it fails to check in case the memory allocation fails. Once the allocation fails, a NULL point will be processed by the parse_option() function, leading grub to crash or, in some rare scenarios, corrupt the IVT data."}], "lastModified": "2025-02-18T20:15:19.177", "sourceIdentifier": "secalert@redhat.com"}
