CVE-2026-22280· NVD / CVE Program· CNA dell

Dell PowerScale OneFS, versions 9.5.0.0 through 9.5.1.5, versions 9.6.0.0 through 9.7.1.10, versions 9.8.0.0 through 9.10.1.3, versions star

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.13% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Dell PowerScale OneFS 9.10.1.4, 9.13.0.0, 9.5.1.6.

Low priority for now. Upgrade to Dell PowerScale OneFS 9.10.1.4, 9.13.0.0, 9.5.1.6 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Dell PowerScale OneFS, versions 9.5.0.0 through 9.5.1.5, versions 9.6.0.0 through 9.7.1.10, versions 9.8.0.0 through 9.10.1.3, versions starting from 9.11.0.0 and prior to 9.13.0.0, contains an incorrect permission assignment for critical resource vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to denial of service.
