Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified) Description: The issue is related to the blk-mq component in the Linux kernel. It occurs when the `q->tag set` is not set up before the cpuhp handler is enabled, leading to a kernel oops. The problem arises from the need to check queue mapping via the tag set in the hctx's cpuhp handler, but the `q->tag set` may not be initialized at that point. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
