CVE-2026-60659

Data tampering and repeatable system crashes

Published Jul 21, 2026 · Updated Jul 21, 2026

Improper access control in Oracle Solaris 11.4 Filesystems allows local users to alter critical data and repeatedly crash or hang the system. Oracle has not disclosed the affected filesystem locus or the incorrect permission or access-control operation behind the flaw. Exploitation requires a low-privileged account with local logon access; confidentiality is unaffected, while data integrity loss and repeatable system interruption are in scope.
