CVE-2026-98315

Summary

The Linux kernel's NTFS filesystem driver has a race condition where runlist updates are not properly protected by locks, potentially allowing attackers to corrupt filesystem metadata and gain arbitrary code execution or data manipulation capabilities.

Exploitability

Exploitation requires local user access with write permissions to an NTFS volume and is moderately difficult to achieve, requiring precise timing of filesystem operations during cluster allocation and runlist modifications.

Blast radius

If exploited, this vulnerability could affect all systems running Linux kernels with NTFS support, potentially leading to complete filesystem corruption or privilege escalation across multiple user sessions.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Apply the kernel patch for the specific fix in the ntfs3 driver, which is part of the Linux kernel version 6.10.1 or later, and ensure all systems are upgraded to at least kernel version 6.10.1.
