CVE-2009-3522 describes a stack-based buffer overflow in the aswMon2.sys driver of Avast! Home and Professional Antivirus versions prior to 4.8.1356. This vulnerability allows a local attacker to trigger a system crash (denial of service) and potentially elevate privileges by sending a specially crafted IOCTL request. With a CVSS score of 7.2, it is considered highly severe due to its local attack vector, low complexity, and potential for complete compromise of confidentiality, integrity, and availability. While not actively exploited in the wild (no KEV entry), public exploit code exists on ExploitDB, though there is minimal community discussion or media coverage surrounding this decade-old vulnerability.
