CVE-2017-18232 (CCN-140428)

Assigned:2017-12-08
Published:2017-12-08
Updated:2019-10-03
Summary: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.
