CVE-2026-72401: Linux

EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux: from 6.19, before 7.1.5 (fixed in 7.1.5)
