CVE-2026-72401
Overview
CVE-2026-72401 is a known-severity vulnerability. It was published on August 15, 2026.
Technical Description
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.
