CVE-2025-38640

CVE-2025-38640 concerns the Linux kernel netfilter BPF path. The issue arises when a BPF program could be executed in nf_hook_run_bpf() without properly disabling migration, which can lead to a crash (splat) in __bpf_prog_run(). The fix introduced is to call bpf_prog_run_pin_on_cpu() in nf_hook_r...
