Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: LoongArch: csum: Fix OoB access in IP checksum code for negative lengths (LoongArch: csum: corregir el acceso OoB en el código de suma de comprobación de IP para longitudes negativas). el commit 69e3a6aa6be2 ("LoongArch: añadir optimización de suma de comprobación para sistemas de 64 bits") provocaría un desplazamiento indefinido y una lectura fuera de los límites. el commit 8bd795fedb84 ("arm64: csum: corregir el acceso OoB en el código de suma de comprobación de IP para longitudes negativas") corrige el mismo problema en ARM64.
