CVE-2023-43636
EVE Doesn't Protect Rootfs
Impact
### Impact Measured boot validates BIOS, grub, kernel cmdline, and initrd but not the entire rootfs. Thus, an attacker can create an EVE-OS rootfs squashfs image with some files modified and take out the disk and replace the existing rootfs image without that being detected by measure boot and remote attestation. ### Patches Fixed in 8.6.0 and 8.12.1-lts ### Workarounds None
