Descriptions
In the Linux kernel before 5.1.13, there is a memory leak in drivers/scsi/libsas/sas_expander.c when SAS expander discovery fails. This will cause a BUG and denial of service.
En el kernel de Linux versiones anteriores a 5.1.13, se presenta una pérdida de memoria en la biblioteca drivers/scsi/libsas/sas_expander.c cuando no se detecta el expansor SAS. Esto provocará un BUG y una denegación de servicio.
A memory leak flaw was found in the Linux kernel. An error in the resource cleanup of the sas_ex_discover_expander function can allow an attacker to induce error conditions that could crash the system. The highest threat from this vulnerability is to system availability.
