CVE-2019-15807 [MEDIUM] CWE-400 kernel: Memory leak in drivers/scsi/libsas/sas_expander.c
kernel: Memory leak in drivers/scsi/libsas/sas_expander.c
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.
Statement: 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).
Mitigation: Mitigation for this issue is either not available or the currently
