CVE-2026-89613: Linux kernel NTFS driver may accept malformed file data
CVE-2026-89613 · published 28 days ago
Summary
The NTFS file-system support in the Linux kernel could mistakenly accept files that contain empty mapping information, which can lead to incorrect file size reporting or data corruption. This affects Linux distributions that use the standard kernel, such as Debian, Ubuntu, and related cloud images. Update the system to the latest kernel version provided by your vendor to apply the fix.
What to do
- Update debian linux to version 7.2.6-1.
- Update linux kernel to version 7.2.4.
- Update linux linux to version b0cc6dbc655e037251874b3e0dd1a760dcf29007 or later.
