CVE-2024-38394 is a medium-severity vulnerability rated 4.3/10 on the CVSS scale. 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.". EPSS estimates a 0.32% chance of exploitation in the next 30 days.
