Kata guest escape: runtime-rs guest-root to host-root escape via virtiofs

Summary In the runtime-rs standalone virtio-fs path, verified here with QEMU and verified with Cloud Hypervisor too, Kata Containers runs host virtiofsd as root with: --sandbox none --seccomp none If an attacker has root-equivalent execution inside the Kata guest VM, they can send raw FUSE reques...

CVE-2026-45983

A flaw was found in the Linux kernel's Network File System version 4 NFSv4 daemon nfsd. When processing NFSv4 requests, delayed responses from idmap lookups can cause requests to be dropped. This issue prevents the session slot from being properly cleared, leading to subsequent client requests...

CVE-2026-44887

CVE-2026-44887 affects Pi.Alert, a WIFI/LAN intruder detector with a web service. The vulnerability arises from the web-based configuration editor allowing arbitrary Python code to be injected into pialert.conf; the background scan daemon loads this file with Python’s exec(), causing the injected...

CVE-2026-44887 Unauthenticated RCE via Python Config File Injection in SaveConfigFile() (Path)

Pi.Alert is a WIFI / LAN intruder detector with web service monitoring. Prior to 2026-05-07, Pi.Alert's web-based configuration editor allows arbitrary Python code to be injected into pialert.conf. Since the background scan daemon loads this file via Python's exec, injected code executes as the...
