Summary
In the Linux kernel, the following vulnerability has been resolved: smb: client: set correct id, uid and cruid for multiuser automounts When uid, gid and cruid are not specified, we need to dynamically set them into the filesystem context used for automounting otherwise they'll end up reusing the values from the parent mount.
