Academic researchers developed ZenHammer, the first variant of the Rowhammer DRAM attack that works on CPUs based on recent AMD Zen microarchitecture that map physical addresses on DDR4 and DDR5 memory chips.
CacheWarp is a new software fault attack on AMD SEV-ES and SEV-SNP. It allows attackers to hijack control flow, break into encrypted VMs, and perform privilege escalation inside the VM.
Google researchers discover 'Reptar,’ a new CPU vulnerability
A new CPU vulnerability, ‘Reptar,’ found by Google researchers, has been patched by Google and Intel. Here’s what you need to know. ... The impact of this vulnerability is demonstrated when exploited by an attacker in a multi-tenant virtualized environment, as the exploit on a guest machine causes the host machine to crash resulting in a Denial of Service to other guest machines running on the same host. Additionally, the vulnerability could potentially lead to information disclosure or privilege escalation.
We have a CPU mystery! We found a way to cause some processors to enter a glitch state where the normal rules don’t apply, but what does that mean…? If you’re interested what can go wrong inside modern CPUs, read on!
Nearly every AMD CPU since 2017 vulnerable to Inception bug
AMD processor users, you have another data-leaking vulnerability to deal with: like Zenbleed, this latest hole can be to steal sensitive data from a running vulnerable machine.
