CVE-2026-72401

bpf: Fix insn_aux_data leak on verifier err_free_env path

In the Linux kernel, the following vulnerability has been resolved:

bpf: Fix insn_aux_data leak on verifier err_free_env path

When bpf_check() allocates env->insn_aux_data successfully but later
fails to allocate env->succ, it jumps directly to err_free_env.

The existing vfree(env->insn_aux_data) sits before the err_free_env
label, so that direct jump bypasses it and leaks insn_aux_data.

Move vfree(env->insn_aux_data) into err_free_env so all early and late
exit paths release it consistently.
