An out-of-bounds memory write flaw was found in the Linux kernel’s UDF file system functionality in the way a user triggers some file operations, which triggers udf_write_fi(). This flaw allows a local user to crash or potentially escalate their privileges on the system.
Отчет
Keeping Moderate, because the actual corruption is out of attacker control, so it means that attack complexity could be high or unpredictable.
Меры по смягчению последствий
To mitigate this issue, prevent the module udf from being loaded. Please see https://access.redhat.com/solutions/41278 for information on how to blacklist a kernel module to prevent it from loading automatically.
