CVE-2026-40572

NovumOS vulnerability CVE-2026-40572: In versions prior to 0.24, Syscall 15 (MemoryMapRange) lets Ring-3 user processes map arbitrary virtual ranges into their address space without validating against forbidden regions, including kernel structures (IDT, GDT, TSS, page tables). This can allow a lo...

CVE-2026-40317

NovumOS (a custom 32-bit OS written in Zig/x86 Assembly) prior to version 0.24 is affected by a local privilege-escalation in the Syscall 12 JumpToUser interface. The vulnerability arises because JumpToUser accepts an arbitrary entry-point address from user-space without validation, enabling any ...

golang: internal/syscall/unix: Root.Chmod can follow symlinks out of the root

A flaw was found in the internal/syscall/unix package in the Go standard library. If the target of the Root.Chmod function is replaced with a symbolic link during execution, specifically after Root.Chmod checks the target but before acting, the chmod operation will be performed on the file the...

ClawLess: A Security Model of AI Agents

Autonomous AI agents powered by Large Language Models can reason, plan, and execute complex tasks, but their ability to autonomously retrieve information and run code introduces significant security risks. Existing approaches attempt to regulate agent behavior through training or prompting, which...

CVE-2026-23241

CVE-2026-23241 affects the Linux kernel audit subsystem: the read class was missing getxattrat()/listxattrat() syscalls, enabling bypass of audit rules (e.g., -w /tmp/test -p rwa). Upstream patches add the missing syscalls to the audit read class. Connected OSV entries report Root:Ubuntu-24.04 an...
