edk2 (2025.02-5) unstable; urgency=medium The EFI_MEMORY_ATTRIBUTE_PROTOCOL is disabled by default in the OVMF32_CODE_4M.secboot.fd image. This is to avoid crashes with guest operating system bootloaders that do not observe proper memory access semantics. If your guest operating system supports it, it is recommended that you use the OVMF32_CODE_4M.secboot.strictnx.fd image instead to provide additional security protection. This security feature will be enabled by default for all *.secboot.fd images in the next release. -- dann frazier Fri, 28 Mar 2025 08:23:47 -0600
