Descriptions
In the Linux kernel, the following vulnerability has been resolved:
crypto: lib/mpi - Fix unexpected pointer access in mpi_ec_init
When the mpi_ec_ctx structure is initialized, some fields are not
cleared, causing a crash when referencing the field when the
structure was released. Initially, this issue was ignored because
memory for mpi_ec_ctx is allocated with the __GFP_ZERO flag.
For example, this error will be triggered when calculating the
Za value for SM2 separately.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: crypto: lib/mpi: corrige el acceso inesperado al puntero en mpi_ec_init Cuando se inicializa la estructura mpi_ec_ctx, algunos campos no se borran, lo que provoca un bloqueo al hacer referencia al campo cuando se lanzó la estructura. Inicialmente, este problema se ignoró porque la memoria para mpi_ec_ctx se asigna con el indicador __GFP_ZERO. Por ejemplo, este error se activará al calcular el valor Za para SM2 por separado.
