CVE-2026-67248
Authenticated stack-based buffer overflow in ADM File Explorer: DoS; possible RCE.
Is CVE-2026-67248 being exploited?
Not confirmed. CVE-2026-67248 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly.

How severe is CVE-2026-67248?
CVE-2026-67248 is rated High with a CVSS score of 8.7. 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-2026-67248?
Yes. A fix has been recorded for CVE-2026-67248. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.

As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
