How severe is CVE-2026-17396?

CVE-2026-17396 is rated Critical with a CVSS score of 9.6. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.

Is there a patch for CVE-2026-17396?

Yes. A fix has been recorded for CVE-2026-17396. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.
