VMW Carbon Black TAU discovered 34 unique vulnerable WDF/WDM drivers (237 file hashes), including ones made by major chip/BIOS/PC makers. By exploiting the drivers, an attacker without privilege may erase/alter firmware, and/or elevate OS privileges. blogs.vmware.com/security/2023/…

#CacheWarp: a new software-based fault attack on AMD EPYC CPUs. It allows attackers to hijack control flow, break into encrypted VMs and perform privilege escalation inside the VM within minutes.
