Technical details
CVE-2026-76104 is an incorrect permission assignment vulnerability in the Dell ObjectScale operating system that allows a high-privileged attacker with network access to cause a denial of service condition. The vulnerability stems from improper permissions on critical OS resources, enabling an authenticated high-privileged user to interfere with system integrity and availability. The attack requires high privilege level but no user interaction. An attacker can exploit this to degrade or disable storage service availability. The vulnerability is remediated in ObjectScale version 4.4.0.0 and later; Dell recommends immediate upgrade via service request.
