CVE-2023-53836
Summary (CVE-2023-53836): In the Linux kernel, a race condition can occur in bpf/sockmap code affecting skb refcnt after locking changes. The backlog path may still hold a reference to a skb that userspace has already consumed (skb_dequeue) and freed, leading to a potential use-after-free. The fi...
