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.

Affected configurations

• linux linux kernel (>= 3.8 < 4.4.294) • linux linux kernel (>= 4.5 < 4.9.292) • linux linux kernel (>= 4.10 < 4.14.257) • linux linux kernel (>= 4.15 < 4.19.219) • linux linux kernel (>= 4.20 < 5.4.163) • linux linux kernel (>= 5.5 < 5.10.83) • linux linux kernel (>= 5.11 < 5.15.6) • linux linux kernel 5.16
