[ Upstream commit9414277a5d] In below code flow, for ingress acl table root ns memory leads to double free. mlx5_init_fs init_ingress_acls_root_ns() init_ingress_acl_root_ns kfree(steering->esw_ingress_root_ns); /* steering->esw_ingress_root_ns is not marked NULL */ mlx5_cleanup_fs cleanup_ingress_acls_root_ns steering->esw_ingress_root_ns non NULL check passes. kfree(steering->esw_ingress_root_ns); /* double free */ Similar issue exist for other tables. Hence zero out the pointers to not process the table again.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
