CVE-2026-53032

The CVE-2026-53032 issue affects the Linux kernel's BPF subsystem, specifically the map_kptr_match_type function. A scalar register stored into a kptr can trigger a NULL dereference when the code branches on btf_is_kernel(reg->btf) before verifying base_type(), since such registers have no BTF...
