VectorAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)
Description: The issue is related to the mpt3sas component of the Linux kernel, which is vulnerable to a resource management error. This error can cause a kernel panic when the driver attempts to access the sas address field of a sas target object without checking if the object is NULL. The vulnerability occurs when a drive is removed while the driver is looping over the shost's sdev list, resulting in the sas target object being freed but its sdev object remaining intact.
Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
