RMPocalypse Now: AMD’s Security Flaw Sparks Chip Chaos!
AMD’s RMPocalypse security flaw could make confidential computing guarantees disappear faster than free donuts in an office break room. Researchers found a single memory write could corrupt the Reverse Map Paging table, leading to a breach of SEV-SNP protections. Chipmakers are scrambling to patch this loophole before hackers start their own RMPocalypse party.
Hot Take:
Oh, AMD, just when you thought you had the perfect plan for world domination in confidential computing, here comes RMPocalypse to rain on your parade! Looks like someone forgot to tick the “super secure” box during the chip design phase. Who knew a race condition could run this fast?
Key Points:
- AMD has issued patches for a security flaw known as RMPocalypse affecting the SEV-SNP technology.
- The flaw exploits a gap in memory write protections within the Reverse Map Paging (RMP) table.
- Affected chips include AMD EPYC™ 7003, 8004, 9004, and 9005 Series Processors, among others.
- The flaw is documented under CVE-2025-0033, with a CVSS score of 5.9.
- Microsoft and Supermicro are also addressing the flaw for their respective systems.
