NVIDIA vGPU software for Linux-style hypervisors contains a vulnerability in the Virtual GPU Manager, where a malicious guest could cause stack buffer overflow. A successful exploit of this vulnerability might lead to code execution, denial of service, escalation of privileges, information disclosure, or data tampering.
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
