Title source: llmExploitation Summary
EIP tracks 2 public exploits for CVE-2026-3437. PoCs published by tihomirocrew.
AI-analyzed exploit summary This repository contains a functional exploit for CVE-2026-3437, demonstrating arbitrary physical memory read/write via the `portwell.sys` driver's IOCTL interface. The PoC leverages `MmMapIoSpace` to achieve local privilege escalation (LPE) to SYSTEM.
Description
An improper restriction of operations within the bounds of a memory buffer vulnerability in Portwell Engineering Toolkits version 4.8.2 could allow a local authenticated attacker to read and write to arbitrary memory via the Portwell Engineering Toolkits driver. Successful exploitation of this vulnerability could result in escalation of privileges or cause a denial-of-service condition.

This repository contains a functional exploit for CVE-2026-3437, demonstrating arbitrary physical memory read/write via the `portwell.sys` driver's IOCTL interface. The PoC leverages `MmMapIoSpace` to achieve local privilege escalation (LPE) to SYSTEM.
This repository contains a functional exploit for CVE-2026-3437, demonstrating arbitrary physical memory read/write operations via a vulnerable driver (PORTWELL_0_1). The PoC interacts with the driver using specific IOCTL codes (0xEA606450 for read, 0xEA60A454 for write) to achieve low-level memory manipulation.
