Summary

Vulnerability in Realtek RtsPer driver for PCIe Card Reader (RtsPer.sys) before 10.0.22000.21355 and Realtek RtsUer driver for USB Card Reader (RtsUer.sys) before 10.0.22000.31274 leaks driver logs containing addresses of kernel mode objects, weakening KASLR.

Risk Assessment

The risk is that an attacker can exploit the kernel address leak to bypass KASLR (Kernel Address Space Layout Randomization), making further system attacks easier.

Recommendation

Immediately update Realtek RtsPer.sys and RtsUer.sys drivers to versions at least 10.0.22000.21355 (PCIe) and 10.0.22000.31274 (USB) or newer.
