HighCVSS 7.8Exploitation Probability (EPSS)
Low risk9th percentile - higher than 9% of all known CVEs
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 writing to kernel memory beyond the SystemBuffer of the IRP.
Risk Assessment
An attacker could exploit this flaw to escalate privileges or cause system instability by writing to kernel memory, posing a serious threat to system integrity and availability.
Recommendation
Immediately update Realtek RtsPer.sys and RtsUer.sys drivers to versions 10.0.22000.21355 and 10.0.22000.31274 or later, respectively.
