The pstrip64.sys driver in EnTech Taiwan PowerStrip <=3.90.736 allows local users to escalate privileges to SYSTEM via a crafted IOCTL request enabling unprivileged users to map arbitrary physical memory into their address space and modify critical kernel structures.
PoC: CVE-2026-29923
A newly discovered vulnerable driver, pstrip64.sys (CVE-2026-29923) allows an unprivileged user to escalate privileges to SYSTEM via a crafted IOCTL request
PoC: CVE-2026-29923
The pstrip64.sys kernel driver exposes an IOCTL that allows low-privileged users to map arbitrary ranges of physical memory into their own virtual address space. This primitive allows full read/write access to the system's physical RAM, enabling attackers to modify critical kernel structures and escalate privileges to NT AUTHORITY\SYSTEM.
