CVE-2026-72192
Local heap overflow in Linux ntfs3 driver enabling privilege escalation
Is CVE-2026-72192 being exploited?
Not confirmed. CVE-2026-72192 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-2026-72192?
CVE-2026-72192 is rated Critical with a CVSS score of 9.8. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.

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.
