The string component in the GNU C Library (aka glibc or libc6) through 2.28, when running on the x32 architecture, incorrectly attempts to use a 64-bit register for size_t in assembly codes, which can lead to a segmentation fault or possibly unspecified other impact, as demonstrated by a crash in __memmove_avx_unaligned_erms in sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S during a memcpy.
El componente string en GNU C Library (también conocido como glibc o libc6) hasta la versión 2.28, cuando se ejecuta en la arquitectura x32, intenta usar de manera incorrecta un registro de 64 bits para "size_t" en códigos de ensamblado, lo que puede provocar un fallo de segmentación u otro impacto no especificado, tal y como queda demostrado con un cierre inesperado en __memmove_avx_unaligned_ermsen sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S durante un memcpy.
