KP Singh 49b18315be bpf: Reject NULL data/sig in bpf_verify_pkcs7_signature ... __bpf_dynptr_data() can return NULL (FILE dynptrs, any non-contiguous backing). bpf_verify_pkcs7_signature() forwards the pointer to verify_pkcs7_signature() unchecked, causing a NULL deref in asn1_ber_decoder() reachable from a sleepable BPF LSM at lsm.s/bpf. NULL-check both pointers and reject with -EINVAL. Mirrors the guards already in kernel/bpf/crypto.c.
