AnalysisAI

Oracle VM VirtualBox 7.2.14 Core component exposes a locally exploitable denial-of-service condition that can be triggered by a high-privileged attacker with logon access to the host infrastructure. Exploitation results in a complete, repeatably triggerable crash or hang of the VirtualBox process, with scope change indicated - meaning the disruption can cascade to guest virtual machines and other co-hosted workloads. …
