Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A Use-After-Free (UAF) issue exists in the rxrpc component. If the skb unshare() function fails to unshare a packet due to an allocation failure within rxrpc input packet(), the skb pointer in the parent function rxrpc io thread() is set to NULL. This sequence leads to a system oops when trace rxrpc rx done() is called.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
