CVE-2024-26822: Linux kernel automount may assign wrong user IDs
CVE-2024-26822 · published 2 years ago

Original advisory text
CVE-2024-26822 in linux - Patched by Root
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.
