CVE-2024-38394 Information

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  new feature not a CVE.\
