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.
The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Issues addressed include buffer overflow, bypass, denial of service, information leakage, memory leak, null pointer, out of bounds read, out of bounds write, privilege escalation, and use-after-free vulnerabilities.
