CVE-2025-39734: 
Linux Debian vulnerability analysis and mitigation

Overview

CVE-2025-39734 is a vulnerability in the Linux kernel that was discovered and disclosed on September 7, 2025. The issue involves the reversion of a commit that replaced inodetrylock with inodelock in the NTFS3 filesystem implementation (NVD).

Technical details

The vulnerability stems from a change in lock acquisition methods in the NTFS3 filesystem. Initially, conditional lock acquisition was removed to address an xfstest bug found during internal testing. However, this led to a deadlock issue reported by syzbot. The resolution involved reintroducing conditional acquisition, as the original xfstest bug was no longer reproducible in kernel version 6.16-rc1 (NVD).

Impact

The vulnerability affects the Linux kernel's NTFS3 filesystem implementation, potentially leading to deadlock conditions that could impact system stability and performance (NVD).

Mitigation and workarounds

The issue has been resolved by reverting commit 69505fe98f198ee813898cbcaf6770949636430b and reintroducing conditional lock acquisition in the NTFS3 filesystem code (NVD).
