CVE-2016-4276 is a critical memory corruption vulnerability in Adobe Flash Player affecting versions before 18.0.0.375, 19.x through 23.x before 23.0.0.162 on Windows and OS X, and before 11.2.202.635 on Linux. This flaw allows attackers to execute arbitrary code or cause a denial of service through unspecified vectors. With a CVSS v3.1 score of 8.8 (High), it presents a significant risk due to its network-based attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. While not listed in CISA's KEV catalog, there is no public exploit code available, and community discussion and media coverage are minimal, suggesting it is not widely exploited in the wild.
