Descriptions

The Serial Attached SCSI (SAS) implementation in the Linux kernel through 4.15.9 mishandles a mutex within libsas, which allows local users to cause a denial of service (deadlock) by triggering certain error-handling code.

La implementación SAS (Serial Attached SCSI) en el kernel de Linux, hasta la versión 4.15.9, gestiona de manera incorrecta un mutex en libsas. Esto permite que usuarios locales provoquen una denegación de servicio (deadlock) desencadenando cierto código de gestión de errores.
