CVE-2023-52616

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2023-52616
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.

Summary
  • (es) 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.
