Until a fixed package is installed, avoid validating RHSM offline tokens through the Cockpit Machines \"Download an OS\" / RHEL image download flow on multi-user hosts where untrusted local users can inspect process metadata. As a system-level mitigation, restrict /proc visibility so unprivileged users cannot read other users' process command lines, for example by remounting /proc with the hidepid=2 mount option; this blocks cross-user observation of the helper process arguments that contain the offline token while the validation flow is running. Fixed packages are being released for the affected streams, and updating to a fixed cockpit-machines package once available for your stream resolves the issue."}],"timeline":[{"lang":"en","time":"2026-05-11T20:27:44.000Z","value":"Reported to Red Hat."},{"lang":"en","time":"2026-09-18T16:35:00.000Z","value":"Made public."}],"credits":[{"lang":"en","value":"This issue was discovered by Found by AISLE in partnership with Red Hat."}],"x_generator":{"engine":"cvelib 1.8.0"}},"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-22T15:17:51.334993Z","id":"CVE-2026-92745","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"providerMetadata":{"shortName":"CISA-ADP","orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","dateUpdated":"2026-09-22T15:18:05.846Z"}}]}}}
