CVE-2021-47565 Information

May 25, 2024 cve

Description

In the Linux kernel the following vulnerability has been resolved:

scsi: mpt3sas: Fix kernel panic during drive powercycle test

While looping over shost’s sdev list it is possible that one of the drives is getting removed and its sas_target object is freed but its sdev object remains intact.

Consequently a kernel panic can occur while the driver is trying to access the sas_address field of sas_target object without also checking the sas_target object for NULL.
