What to do, per Debian release
Debian's own status for CVE-2024-38625 in every release this site tracks, and what each one means in practice. Every status below is the one the Debian Security Team publishes for this CVE. source
| Release | Status | Version | What this means |
|---|---|---|---|
| Debian 12bookworm | vulnerable | 6.1.190-1 | No fix published anywhere yet, neither in Debian nor upstream for the series bookworm tracks. Watch the Debian tracker page for this CVE. Advisories for bookworm have historically landed a median of 23 days after publication. |
| Debian 13trixie | fixed | 6.9.7-1 | Update the kernel and reboot. Fixed in 6.9.7-1. A running kernel keeps the old code until the machine restarts. |
| Debian 14forky | fixed | 6.9.7-1 | Update the kernel and reboot. Fixed in 6.9.7-1. A running kernel keeps the old code until the machine restarts. |
| Debian unstablesid | fixed | 6.9.7-1 | Update the kernel and reboot. Fixed in 6.9.7-1. A running kernel keeps the old code until the machine restarts. |
The vulnerability
What the bug is
It can be NULL if bmap is called.
Where it lives
The fix touches these files. If the subsystem is one you do not use, the practical exposure is lower, though the package is still the vulnerable one.

Check it on the machine
grep -w CONFIG_NTFS3_FS /boot/config-$(uname -r)Reads the booted kernel's own configuration, on the machine and nowhere else. =y is built in, =m is a module, and an is not set line means the code is not there.
lsmod | grep -w ntfs3Prints a line if that module is loaded right now, and nothing if it is not. One that is not loaded can still be loaded later by anything that needs it.
Show whether Debian builds this, per release
Debian does not build this code in 3 releases. It does build it in 1 release, so the answer depends on which release the machine runs.
- bookwormn
- trixiem
- forky, sidn
- n
- not enabled on any flavour - this release does not build the code
- m
- a loadable module on every flavour - check lsmod, can be blacklisted
- Build switch
- CONFIG_NTFS3_FS
From the configuration Debian publishes for every kernel flavour it builds. It covers only the architectures Debian ships a linux-config package for, and nothing about a kernel you built yourself.

Why the CNA scored it this way
The kernel CNA published no CVSS vector and no reasoning for CVE-2024-38625, which is why it is shown as unrated rather than given an invented score. 6,405 of the 20,413 CVEs here carry reasoning; this is not one of them.
