Описание
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.
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.
Отчет
This issue is rated as having Low impact because of the preconditions needed to trigger the error/resource cleanup code path (system-wide out-of-memory condition, high privileges or physical access).
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
