CVE-2026-5747

An out-of-bounds write issue in the virtio PCI transport in Firecracker 1.13.0 through 1.14.3 and 1.15.0 on x8664 and aarch64 might allow a local guest user with root privileges to crash the Firecracker VMM process or potentially execute arbitrary code on the host via modification of virtio queue...

CVE-2026-34197

A flaw was found in Apache ActiveMQ Broker and Apache ActiveMQ. An authenticated attacker can exploit this vulnerability by sending a specially crafted discovery Uniform Resource Identifier URI to the Jolokia JMX-HTTP bridge, which is exposed on the web console. This allows the attacker to bypass...

Improper Privilege Management

kubevirt.io/kubevirt is vulnerable to improper privilege management. The vulnerability is due to excessive permissions granted to the virt-handler service account, which allows an attacker to abuse update and patch capabilities to force VMI migration or schedule privileged pods onto a compromised...

Logic Flaw

KubeVirt is vulnerable to a logic flaw. The vulnerability is due to improper validation in the virt-controller, which allows an attacker to create a malicious pod with matching labels to mislead the controller and disrupt VMI management, leading to denial-of-service...
