Descriptions
In the Linux kernel, the following vulnerability has been resolved:
landlock: Fix d_parent walk
The WARN_ON_ONCE() in collect_domain_accesses() can be triggered when
trying to link a root mount point. This cannot work in practice because
this directory is mounted, but the VFS check is done after the call to
security_path_link().
Do not use source directory's d_parent when the source directory is the
mount point.
