CVE-2024-35875

CVE-2024-35875 concerns the Linux kernel’s x86/coco RNG seeding feature. The affected area requires seeding the RNG with 256 bits of RDRAND data at boot for CoCo systems, because the CoCo threat model assumes an untrusted host and limited entropy sources. If RDRAND is broken or unavailable, the i...
