CVE-2026-53233

Beschreibung

In the Linux kernel, the following vulnerability has been resolved: netdev: fix double-free in netdev_nl_bind_rx_doit() Sashiko flags that genlmsg_reply() always consumes the skb. The error path calls nlmsg_free(rsp) so we can-t jump directly to it. Let-s not unbind, just propagate the error to the user. This is the typical way of handling genlmsg_reply() failures. They shouldn-t happen unless user does something silly like calling the kernel with an already-full rcvbuf.
