Local system crash via driver heap overflow
Published Aug 14, 2025 · Updated Aug 18, 2025
Heap-based buffer overflow in Netskope Client before 129.0.0, except 126.0.9 and later, allows local users to crash Windows. Netskope has not disclosed which driver interface or input epdlpdrv.sys mishandles when overflowing heap memory. Exploitation requires low-privileged local access and Endpoint DLP, and a successful attempt causes a Blue Screen of Death on the local machine.
