CVE-2022-21524Network attack vector

Authenticated data modification and service disruption

Published Jul 19, 2022 · Updated Sep 24, 2024

Filesystem vulnerability in Oracle Solaris 11 allows remote authenticated users to alter data and crash the system through SMB. Oracle identifies the filesystem component and SMB protocol but has not published the faulty operation or input that triggers the flaw. A low-privileged SMB account is required; successful exploitation reads, changes, inserts, or deletes some accessible data and causes a hang or repeatable crash.
