Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)
Description: A potential NULL pointer dereference exists in the zd mac tx to dev() function due to a race condition between checking the skb queue length and unconditionally dequeuing an skb. Specifically, skb dequeue() can return NULL, and this NULL pointer is subsequently passed to and dereferenced by the zd mac tx status() function. This issue was found by Linux Verification Center (linuxtesting.org) with SVACE.
Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
