CVE-2025-30690

Local system takeover via undisclosed filesystem flaw

Published Apr 15, 2025 · Updated Feb 26, 2026

Improper access control in the Oracle Solaris 11 Filesystem allows local users with high privileges to take over the operating system. Oracle has not disclosed the affected filesystem locus or the access-control operation that mishandles untrusted input. Exploitation requires a highly privileged local account, high complexity, and interaction by another person; successful attacks grant operating-system takeover and can affect additional products.
