  3. CVE-2023-53124
In the Linux kernel, the following vulnerability has been resolved: scsi: mpt3sas: Fix NULL pointer access in mpt3sas_transport_port_add() Port is allocated by sas_port_alloc_num() and rphy is allocated by either sas_end_device_alloc() or sas_expander_alloc(), all of which may return NULL. So we need to check the rphy to avoid possible NULL pointer access. If sas_rphy_add() returned with failure, rphy is set to NULL. We would access the rphy in the following lines which would also result NULL pointer access.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: scsi: mpt3sas: Se corrige el acceso a puntero nulo en mpt3sas_transport_port_add(). El puerto se asigna mediante sas_port_alloc_num() y el rphy se asigna mediante sas_end_device_alloc() o sas_expander_alloc(), lo que puede devolver un valor nulo. Por lo tanto, es necesario comprobar el rphy para evitar un posible acceso a puntero nulo. Si sas_rphy_add() falla, el rphy se establece en nulo. Accederíamos al rphy en las siguientes líneas, lo que también resultaría en un acceso a puntero nulo.
