NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-6_12_0-160000_29-default package and not the kernel-livepatch-6_12_0-160000_29-default package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

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.
