AnalysisCVE.org

In the Linux kernel, the following vulnerability has been resolved:

ntfs: move attribute payload before shrinking its record

ntfs_new_attr_flags() resizes the non-resident attribute record before moving its name and mapping pairs to their shorter-header offsets when compression or sparse state is cleared.

Shrinking the record first moves the following attribute over the tail of the old record. The subsequent memmove() therefore copies bytes from that following attribute instead of the old mapping pairs. Re-enabling compression on an empty file persists those bytes as a malformed mapping pairs array, which ntfsck reports as a missing or invalid run length.

Move the payload before shrinking the record, while retaining the existing resize-before-move ordering when growing it.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.

Attack Technique

Information Disclosure MEDIUM

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
