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 allows for the leakage of kernel memory from both the stack and the heap.
Risk Assessment
Kernel memory leakage can expose sensitive system data such as passwords, encryption keys, or other confidential information, increasing the risk of privilege escalation and further attacks.
Recommendation
Immediately update the Realtek RtsPer.sys and RtsUer.sys drivers to version 10.0.22000.21355 or later and 10.0.22000.31274 or later, respectively.
