Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A double-free issue exists in the netdev nl bind rx doit() function. This occurs because genlmsg reply() always consumes the socket buffer (skb), but the error path incorrectly calls nlmsg free(rsp), leading to the memory being freed twice. This situation typically arises when the kernel is called with an already-full receive buffer (rcvbuf).
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
