Description OSIDB Bzimport 2025-07-30 07:01:08 UTC 
In the Linux kernel, the following vulnerability has been resolved:

do_change_type(): refuse to operate on unmounted/not ours mounts

Ensure that propagation settings can only be changed for mounts located
in the caller's mount namespace. This change aligns permission checking
with the rest of mount(2).
