Hello,
Linux kenrel built with the BPF interpreter support in the networking core is vulnerable to an out of bounds buffer access flaw. It occurs when accessing a netlink attribute from the skb->data buffer.
An unprivileged user/program could use this flaw to crash the system kernel resulting in DoS.
