What is CVE-2022-25477?
The vulnerability affects the Realtek RtsPer and RtsUer drivers used in PCIe and USB card readers, respectively. It allows an attacker to leak driver logs that may expose kernel mode object addresses. The leakage of these addresses can compromise Kernel Address Space Layout Randomization (KASLR), a key security feature designed to protect against various types of attacks. This exploit could lead to increased risks of privilege escalation and other security threats. Users are urged to update their drivers to the latest versions to mitigate potential exposure.
Exploit Proof of Concept (PoC)
PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
