CVE-2026-40317: Improper Privilege Management
NovumOS is a custom 32-bit operating system written in Zig and x86 Assembly. In versions prior to 0.24, Syscall 12 JumpToUser accepts an arbitrary entry point address from user-space registers without validation, allowing any Ring 3 user-mode process to jump to kernel addresses and execute...
NovumOS ๅฎๅ จๆผๆด
NovumOS is an 32-bit protected mode operating system developed by MinecAnton209. Versions of NovumOS prior to 0.24 contained security vulnerabilities; these vulnerabilities stemmed from Syscall 12 not verifying the entry address provided by the user space, which could lead to local privilege...
PT-2026-33549
Name of the Vulnerable Software and Affected Versions NovumOS versions prior to 0.24 Description Syscall 15 'MemoryMapRange' allows Ring 3 user-mode processes to map arbitrary virtual address ranges into their address space without validating against forbidden regions. This includes critical kern...
PT-2026-44319
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to kernel-devel-7.0.11-1.1 Description An issue exists in the tracepoint add func function where the subsystem's ext-regfunc is invoked before attempting to install a new probe via func add. If func add fails, such ...
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...

๐ LuaJIT 2.1.1774638290 Arbitrary Code Execution
LuaJIT's Foreign Function Interface FFI provides unrestricted access to native C functions including syscall, mmap, mprotect and arbitrary shared library loading. When FFI is accessible to untrusted Lua code in embedding scenarios OpenResty, Redis, game engines, IoT, an attacker can achieve...
PT-2026-34388
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description In the s390 architecture, the syscall number is directly controlled by userspace. The absence of an array index nospec boundary allows for potential access beyond the syscall function...
The vulnerability of the evlist__free_syscall_tp_fields() function in the tools/perf/builtin-trace.c module of the Linux operating system allows a hacker to cause a service failure.
The vulnerability of the evlistfreesyscalltpfields function in the tools/perf/builtin-trace.c module of the Linux kernel is related to incorrect initialization of resources. Exploiting this vulnerability could allow an attacker to cause a service failure...
UBUNTU-CVE-2026-23241
In the Linux kernel, the following vulnerability has been resolved: audit: add missing syscalls to read class The "at" variant of getxattr and listxattr are missing from the audit read class. Calling getxattrat or listxattrat on a file to read its extended attributes will bypass audit rules such...
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...
