Move the overflow check before the write.\n\nSide note, emitting a warning splat with a backtrace might be overkill\nhere, but prefer not changing the behaviour other than not doing the\noverrun.\n\nDiscovered using AI-assisted static analysis confirmed by Intel Product\nSecurity.\n\n(cherry picked from commit 9284ab3b6e776c315883ac2611283d263c9460fd)",
