Have you verified that commit ac6800e279a2 ("fs: Add missing umask strip in vfs_tmpfile") doesn't already fix this?
No, I havn't - I submitted this patch already several years ago, but it was never merged, and since then, I've been carrying this patch around in all kernels I ever used. While doing some other kernel work this week, I decided to resubmit it, because I thought it's a security vulnerability to ignore the umask. But thanks, it's a good hint, I'll check that 2022 commit.
