  3. CVE-2021-47176
In the Linux kernel, the following vulnerability has been resolved: s390/dasd: add missing discipline function Fix crash with illegal operation exception in dasd_device_tasklet. Commit b72949328869 ("s390/dasd: Prepare for additional path event handling") renamed the verify_path function for ECKD but not for FBA and DIAG. This leads to a panic when the path verification function is called for a FBA or DIAG device. Fix by defining a wrapper function for dasd_generic_verify_path().

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: s390/dasd: agregar función de disciplina faltante. Se corrigió falla con excepción de operación ilegal en dasd_device_tasklet. El commit b72949328869 ("s390/dasd: Prepárese para el manejo de eventos de ruta adicional") cambió el nombre de la función verificar_ruta para ECKD pero no para Logística de Amazon y DIAG. Esto provoca pánico cuando se llama a la función de verificación de ruta para un dispositivo FBA o DIAG. Para solucionarlo, defina una función contenedora para dasd_generic_verify_path().
