CVE-2026-99018

The Linux kernel is vulnerable to an unprivileged kernel arbitrary-write and control-flow-hijack primitive when CONFIG_SHADOW_CALL_STACK is enabled on riscv architecture. The root cause lies in handle_exception(), which incorrectly uses the user-writable tp register to determine if a trap origina...

NimicStack

NimicStack NimicStack is the pure Nim implementation of Call Stack Spoofing technique to mimic legitimate programs. Whole project is based on the PoC shared by WithSecure Labs Compilation You can directly compile the source code with the following command: nim c -d=mingw --app=console --cpu=amd64...

Shelter

Shelter Shelter is a completely weaponized sleep obfuscation technique that allows to fully encrypt your in-memory payload making an extensive use of ROP. This crate comes with the following characteristics: AES-128 encryption. Whole PE encryption capability. Removal of execution permission durin...

LazyHook

Overview LazyHook is a stealthy API hooking framework that bypasses Host Intrusion Prevention Systems HIPS through call stack spoofing. By leveraging CPU-level hardware breakpoints and Vectored Exception Handling, it executes arbitrary code as if it originated from trusted, Microsoft-signed...

SilentMoonwalk

SilentMoonwalk PoC Implementation of a fully dynamic call stack spoofer TL;DR SilentMoonwalk is a PoC implementation of a fully dynamic call stack spoofer, implementing a technique to remove the original caller from the call stack, using ROP to desynchronize unwinding from control flow. Authors...

ThreadStackSpoofer

Thread Stack Spoofing / Call Stack Spoofing PoC A PoC implementation for an advanced in-memory evasion technique that spoofs Thread Call Stack. This technique allows to bypass thread-based memory examination rules and better hide shellcodes while in-process memory. Intro This is an example...

CallStackSpoofer

CallStackSpoofer This repository demonstrates a PoC implementation to spoof arbitrary call stacks when making system calls. For a full technical walkthrough please see the accompanying blog post here: https://labs.withsecure.com/blog/spoofing-call-stacks-to-confuse-edrs. By default it contains...

CallStackMasker

CallStackMasker This repository demonstrates a PoC technique for dynamically spoofing call stacks using timers. Prior to our implant sleeping, we can queue up timers to overwrite its call stack with a fake one and then restore the original before resuming execution. Hence, in the same way we can...

CVE-2020-37287

Vyper versions prior to 0.2.6 are susceptible to a call stack corruption vulnerability. The root cause is an incorrect assumption by the compiler that each subtype size is 32, which occurs when complex types with non-base members are passed as function arguments. This flaw leads to corrupted func...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: scs: A wrong parameter was fixed in scsmagic. The scsmagic function requires a void variable, but a struct taskstruct is provided instead. taskscstsk represents the starting address of the task’s shadow call stack, and...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: sched/scs: The task stack state is reset in bringupcpu. When a CPU is hot-plugged, the idle task on that CPU calls several layers of C code before finally leaving the kernel. When KASAN is in use, a “poisoned” shadow is left behi...
