Supported versions that are affected are 19.3-19.32, 21.3-21.23 and 23.4.0-23.26.3. Easily exploitable vulnerability allows unauthenticated attacker with access to the physical communication segment attached to the hardware where the Portable Clusterware executes to compromise Portable Clusterware. While the vulnerability is in Portable Clusterware, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Portable Clusterware. (CVE-2026-71063, CVE-2026-71064) - Vulnerability in the Portable Clusterware component of Oracle Database Server. Supported versions that are affected are 19.3-19.32, 21.3-21.23 and 23.4.0-23.26.3.
