The cited commit introduced the following coverity issue at function
mlx5_tc_ct_rule_to_tuple_nat:
- Memory - corruptions (OVERRUN)
Overrunning array "tuple->ip.src_v6.in6_u.u6_addr32" of 4 4-byte
elements at element index 7 (byte offset 31) using index
"ip6_offset" (which evaluates to 7).
In case of IPv6 destination address rewrite, ip6_offset values are
between 4 to 7, which will cause memory overrun of array
"tuple->ip.src_v6.in6_u.u6_addr32" to array
"tuple->ip.dst_v6.in6_u.u6_addr32".
Fixed by writing the value directly to array
"tuple->ip.dst_v6.in6_u.u6_addr32" in case ip6_offset values are
between 4 to 7.
Fixes: bc562be967 ("net/mlx5e: CT: Save ct entries tuples in hashtables")

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.
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.
