[ 63.018142] ---[ end trace ]--- Historically, the signed integer overflow sanitizer did not work in the kernel due to its interaction with `-fwrapv` but this has since been changed [1] in the newest version of Clang; It was re-enabled in the kernel with Commit 557f8c582a9ba8ab ("ubsan: Reintroduce signed overflow sanitizer"). Let's rework this overflow checking logic to not actually perform an overflow during the check itself, thus avoiding the UBSAN splat. [1]: https://github.com/llvm/llvm-project/pull/82432

[ 63.018142] ---[ end trace ]--- Hist\u00f3ricamente, el sanitizante de desbordamiento de enteros con signo no funcionaba en el kernel debido a su interacci\u00f3n con `-fwrapv` pero esto se ha cambiado desde entonces [1] en la versi\u00f3n m\u00e1s reciente de Clang; Se volvi\u00f3 a habilitar en el kernel con el commit 557f8c582a9ba8ab (\\\"ubsan: reintroducir el sanitizante de desbordamiento firmado\\\"). Modifiquemos esta l\u00f3gica de verificaci\u00f3n de desbordamiento para no realizar un desbordamiento durante la verificaci\u00f3n en s\u00ed, evitando as\u00ed el s\u00edmbolo de UBSAN.
