CVE-2024-47675 is a use-after-free vulnerability in the Linux kernel BPF function bpf_uprobe_multi_link_attach(). When bpf_link_prime() fails, the error path frees an array of bpf_uprobe structures without calling bpf_uprobe_unregister(). This frees bpf_uprobe->consumer while leaving it linked in uprobe->consumers, creating a dangling reference, and also leaks the associated bpf_uprobe->uprobe reference.
