Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: null_blk: corrige la validación del tamaño del bloque. El tamaño del bloque debe estar entre 512 y PAGE_SIZE y ser una potencia de 2. La verificación actual no valida esto, así que actualice la verificación. Sin este parche, null_blk tendría un error debido a la eliminación del puntero nulo cuando se carga con bs=1536 [1]. [axboe: elimine las llaves innecesarias y la comprobación != 0]
