Subject: [GIT PULL] hardening fixes for v6.18-rc1

Hi Linus,

Please pull these two hardening fixes for v6.18-rc1. After this, I'm
expecting 1 more CONFIG_CFI_CLANG -> CONFIG_CFI "passing in the night"
fix once the x86/core PR lands:
https://lore.kernel.org/lkml/20251003221030.GA1162775@ax162/

Thanks!

-Kees
