CVE-2020-3653 is a critical buffer over-read vulnerability in Qualcomm's Windows WLAN driver, affecting several Snapdragon Compute and Connectivity platforms including MSM8998, QCA6390, SC7180, SC8180X, and SDM850. This flaw stems from insufficient length checks on user-supplied data, allowing an unauthenticated attacker to remotely execute code or cause a denial of service. With a CVSS score of 9.1 (CRITICAL), it presents a significant risk due to its network-based attack vector and low complexity. While no public exploits, Metasploit modules, or Nuclei templates are currently available, and there is minimal community discussion, its critical severity warrants attention.
