A vulnerability in the vmxnet3 virtual network adapter used by multiple VMware products could allow a local attacker on a guest system to execute arbitrary code on the host system.
The vulnerability is due to the use of uninitialized stack memory in the vmxnet3 virtual network adapter of affected VMware products. An attacker could exploit this vulnerability by sending a request that submits malicious input to the targeted host system. A successful exploit could allow the attacker to execute arbitrary code on the host system.
Proof-of-concept (PoC) code that demonstrates an exploit of this vulnerability is publicly available.
VMware has confirmed the vulnerability and released software updates.
