Google has awarded a $250,000 bounty for the discovery of a high-severity vulnerability in the Linux kernel. The flaw specifically allowed for "guest VM escapes," a critical security breach where an attacker could break out of a virtual machine's isolated environment to gain access to the underlying host system.

The vulnerability underscores the ongoing risks associated with virtualization, where the failure of a boundary between a guest and a host can compromise the entire infrastructure of a cloud provider or a local server.
