Attack conditions (Source advisory, CVSS 3.1): Local · Low privileges required · No user interaction required

What an attacker can do

The active user can mount removable UDF media without CAP_SYS_ADMIN, an unprivileged local user can supply the crafted filesystem and trigger the panic by truncating a writable file on it. Source advisory’s CVSS 3.1 assessment (base score 7.8/10) rates confidentiality, integrity and availability impact as high.
