      "value": "The malloc function in the GNU C Library (aka glibc or libc6) 2.26 could return a memory block that is too small if an attempt is made to allocate an object whose size is close to SIZE_MAX, potentially leading to a subsequent heap overflow. This occurs because the per-thread cache (aka tcache) feature enables a code path that lacks an integer overflow check."

      "value": "La funci\u00f3n malloc en GNU C Library (tambi\u00e9n conocida como glibc o libc6) 2.26 podr\u00eda devolver un bloque de memoria demasiado peque\u00f1o si se intenta asignar un objeto cuyo tama\u00f1o se acerca a SIZE_MAX. Esto podr\u00eda conducir a un desbordamiento de memoria din\u00e1mica (heap). Esto ocurre debido a que la caracter\u00edstica de cach\u00e9 per-thread (tambi\u00e9n conocida como tcache) habilita una ruta de c\u00f3digo a la que le falta una comprobaci\u00f3n de desbordamiento de enteros."
