A browser-to-kernel exploit chain is alarming not because it is flashy, but because it turns a routine click into a test of every security boundary a mobile platform depends on.
GhostLock Turns a Quiet Linux Code Path Into a Root-Access Trap
A reported kernel memory-safety bug in Linux locking code shows how local access, not just network attacks, can still become a path to host takeover and container breakouts.
Bad Epoll Turns a Kernel Shortcut Into a Root-Access Problem
A Linux epoll flaw described as a zero-day shows how a small race in kernel teardown can become a local privilege-escalation path on desktops, servers, and Android devices.
When an AI Desktop Sandbox Breaks, the Isolation Story Gets Thin Fast
A reported sandbox-escape chain in a Windows AI client shows how one local foothold can push past VM boundaries and make outbound controls far less meaningful.

A critical flaw in Cisco Identity Services Engine shows how a validation mistake inside a policy platform can cross from application logic into the underlying operating system.
When the Gatekeeper Breaks: Ivanti Sentry Flaw Is Being Turned Into Root Access
A recently patched maximum-severity weakness in an internet-facing mobile gateway is now under active attack, and the risk is bigger than a single crashed appliance.
Inside the UniFi OS Chain That Could Turn a Login Barrier into Root Control
A reported pre-authentication chain in UniFi OS shows how already patched bugs can still combine into a high-risk control-plane compromise.
When a Management Plane Breaks Open, the Host Is the Prize
A critical flaw chain in UniFi OS Server shows how broken access control, path handling, and command injection can collapse a trusted admin surface into root-level risk.
The Cisco Control Room Bug That Can Turn Admin Access Into Root
CVE-2026-20245 shows why a flaw in SD-WAN management software matters far beyond one server: if the control plane falls, the network can inherit the damage.
