NTFS-3G CVE-2026-46572

The primary remediation is to upgrade ntfs-3g to a version released after 2026.2.25 once a patched release is published by the upstream project or your Linux distribution. Monitor the ntfs-3g upstream repository and Ubuntu Security Notices (USN) for the patched package version - no exact fix version is confirmed in the available data. As an interim compensating control, consider removing the SUID bit from the ntfs-3g binary (chmod -s /usr/bin/ntfs-3g) on systems where unprivileged NTFS mounting is not required; this prevents exploitation but will require root or sudo for all NTFS mount operations. On systems where users must not supply arbitrary disk images, enforce filesystem mounting policies via udev rules or mount namespace restrictions. If ntfs-3g is not needed at all (e.g., systems that never use NTFS), removing the package entirely eliminates the attack surface. The Ubuntu vendor report suggests a patched package is likely forthcoming through standard distribution security channels; check the Ubuntu Security page for USN advisories.
