Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

The Linux kernel allows user-space processes to enable mitigations by calling prctl with PRSETSPECULATIONCTRL, which disables the speculation feature, as well as through the use of seccomp. We noticed that on virtual machines of at least one major cloud provider, the kernel still left the victim...

EUVD-2026-10360

A security issue was discovered in ingress-nginx where the nginx.ingress.kubernetes.io/rewrite-target Ingress annotation can be used to inject configuration into nginx. This can lead to arbitrary code execution in the context of the ingress-nginx controller, and disclosure of Secrets accessible t...

CVE-2026-3288

Summary: CVE-2026-3288 concerns ingress-nginx where the nginx.ingress.kubernetes.io/rewrite-target annotation can inject configuration into nginx, enabling arbitrary code execution in the ingress-nginx controller and disclosure of Secrets accessible to the controller. The default installation can...
