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.
