Description

An issue was discovered in the Linux kernel before 4.20. There is a race condition in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free. A flaw was found in the Linux kernel’s implementation of the SAS expander subsystem, where a race condition exists in the smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c. An attacker could abuse this flaw to corrupt memory and escalate privileges.
