A vulnerability in Oracle MySQL Server versions 8.0.0 through 8.0.41, 8.4.0 through 8.4.4, and 9.0.0 through 9.2.0 allows a high-privileged attacker with network access to cause a denial of service by hanging or crashing the server. The vulnerability affects availability but does not impact confidentiality or integrity. Oracle has released patches addressing this issue in their April 2025 Critical Patch Update.
