Merge tag 'bounds-fixes-v5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull bounds fixes from Kees Cook:
"These are a handful of buffer and array bounds fixes that I've been
carrying in preparation for the coming memcpy improvements and the
enabling of '-Warray-bounds' globally.
There are additional similar fixes in other maintainer's trees, but
these ended up getting carried by me. :)"
