CVE-2025-4657

Elevated local code execution via heap overflow

Published Jul 17, 2025 · Updated Jul 17, 2025

Heap-based buffer overflow in Lenovo Protection Driver before 5.1.1110.4231 allows local users with elevated privileges to execute code. The published advisory identifies lrtp.sys as the affected driver but does not disclose the vulnerable function, triggering input, or incorrect memory operation. The driver is installed by Lenovo PC Manager, Lenovo Browser, and Lenovo App Store on Windows; exploitation requires elevated local privileges and grants arbitrary code execution in the driver's security context.
