Name of the Vulnerable Software and Affected Versions:

Linux kernel (affected versions not specified)

Description:

The `do change type()` function previously allowed operations on unmounted or improperly owned mounts. This issue has been resolved by ensuring that propagation settings can only be modified for mounts within the caller's mount namespace, aligning permission checks with the rest of the `mount(2)` system call.

Recommendations:

At the moment, there is no information about a newer version that contains a fix for this vulnerability.
