| Name | CVE-2024-38394 |
| Description | Mismatches in interpreting USB authorization policy between GNOME Settings Daemon (GSD) through 46.0 and the Linux kernel's underlying device matching logic allow a physically proximate attacker to access some unintended Linux kernel USB functionality, such as USB device-specific kernel modules and filesystem implementations. NOTE: the GSD supplier indicates that consideration of a mitigation for this within GSD would be in the context of "a new feature, not a CVE." |

gnome-settings-daemon would rather be a new feature but not a vulnerability
fixing. The CVE assignment is disputed upstream with this context.
