CVE-2026-64353

CVE-2026-64353 affects the Linux kernel BPF subsystem. The issue arises when an ARRAY_OF_MAPS uses an inner map template created with BPF_F_INNER_MAP; a concrete inner array with a different max_entries can replace the template, causing the verifier to mis-handle nullness of lookup results. The k...
