Summary
An issue was discovered in the Linux kernel before 6.1.11. In net/netrom/af_netrom.c there is a use-after-free because accept is also allowed for a successfully connected AF_NETROM socket. However in order for an attacker to exploit this the system must have netrom routing configured or the attacker must have the CAP_NET_ADMIN capability.
