Broadcom has shipped emergency patches for three critical VMware vulnerabilities, including two authentication bypasses and a VM escape.

The fixes landed late Tuesday night, and internal documents show the company quietly pushed the updates to its download portals without a coordinated disclosure window. Engineers close to the project say the VM escape is the one that has security teams most concerned, because it allows an attacker with code execution inside a guest operating system to break out and hit the hypervisor itself. That is about as bad as it gets for virtualized infrastructure.

The other two flaws are authentication bypasses in VMware’s identity and access management layer. Successful exploitation would let a remote, unauthenticated attacker bypass login checks and gain administrative control over the affected appliance. The rollout has been anything but smooth, with several customers reporting that the initial patch bundles fail to apply cleanly on systems running older ESXi builds. Broadcom has acknowledged the issue and is advising administrators to review the release notes carefully before deploying.

The disclosure traces back to a report from BleepingComputer (@BleepinComputer), which broke the news on July 30. The outlet noted that Broadcom did not publish CVSS scores for all three flaws, which is unusual. Security researchers following the advisory believe the VM escape could carry a near-maximum severity rating, though that remains unconfirmed until Broadcom releases full technical detail.

What matters here is the blast radius. VMware is still the backbone of most enterprise private clouds and a significant portion of government infrastructure. A VM escape in the wild would not just be a breach of one server — it would give an attacker a beachhead on the underlying hardware, bypassing the isolation that makes virtualization safe in the first place. The authentication bypasses are arguably worse for day-to-day operations, because they lower the bar for entry from "already inside the network" to "anyone with network access."

The immediate next step for every vSphere administrator is to patch the management interfaces first, then the ESXi hosts. Broadcom says the full security bulletin will drop within the next two weeks, and the company is expected to clarify whether any of these flaws were exploited in the wild prior to disclosure. Until then, the assumption in security circles is that exploit code is already being written, if not circulating.
