CVE-2017-18232

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.

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

It was discovered that a race condition existed in the ARC EMAC ethernet driver for the Linux kernel, resulting in a use-after-free vulnerability. An attacker could use this to cause a denial of service. It was discovered that a race condition existed in the Serial Attached SCSI implementation in the Linux kernel when handling certain error conditions. A local attacker could use this to cause a denial of service. Various other issues were also addressed.
