CVE-2023-53108: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: net/iucv: Fix size of interrupt data iucvirqdata needs to be 4 bytes larger. These bytes are not used by the iucv module, but written by the z/VM hypervisor in case a CPU is deconfigured. Reported as: BUG dma-kmalloc-64 Not...

The vulnerability of Xen hypervisors relates to the incorrect sequence of processor instructions, allowing attackers to gain unauthorized access to protected information.

The vulnerability of Xen hypervisors is related to an incorrect sequence of processor instructions, due to the absence of the ENDBR instruction and a prologue/eepilog for CFI schemes based on hash. Exploiting this vulnerability can allow an attacker operating remotely to gain unauthorized access ...

The vulnerability of Xen hypervisors relates to the mutual blocking of execution streams, which allows a malicious actor to cause a service failure.

Citrix DaaS - Hosting Connection "Username and Password Not Recognized" Error

When attempting to establish or test a hosting connection within your virtualization environment, the system reports an authentication failure with the following error message: "The username and password combination supplied for this connection was not recognized." This error indicates that the...

Regulating AI Behavior with a Hypervisor

Interesting research: "Guillotine: Hypervisors for Isolating Malicious AIs." Abstract :As AI models become more embedded in critical sectors like finance, healthcare, and the military, their inscrutable behavior poses ever-greater risks to society. To mitigate this risk, we propose Guillotine, a...

Guillotine: Hypervisors for Isolating Malicious AIs

As AI models become more embedded in critical sectors like finance, healthcare, and the military, their inscrutable behavior poses ever-greater risks to society. To mitigate this risk, we propose Guillotine, a hypervisor architecture for sandboxing powerful AI models -- models that, by accident o...

dpdk: Denial Of Service from malicious guest on hypervisors using DPDK Vhost library

An out-of-bounds read vulnerability was found in DPDK's Vhost library checksum offload feature. This issue enables an untrusted or compromised guest to crash the hypervisor's vSwitch by forging Virtio descriptors to cause out-of-bounds reads. This flaw allows an attacker with a malicious VM using...
