As seen in the later part of the function, skb = fmdev->resp_skb;\nwhen the invalid fmdev->resp_skb passes the check, a null pointer\ndereference error may occur at line 478, evt_hdr = (void *)skb->data;\n\nTo address this issue, it is recommended to include the validity check of\nfmdev->resp_skb within the locked section of the function. This\nmodification ensures that the value of fmdev->resp_skb does not change\nduring the validation process, thereby maintaining its validity.\n\nThis possible bug is found by an experimental static analysis tool\ndeveloped by our team. This tool analyzes the locking APIs\nto extract function pairs that can be concurrently executed, and then\nanalyzes the instructions in the paired functions to identify possible\nconcurrency bugs including data races and atomicity violations."
