Title
libbpf: Fix accessing BTF.ext core_relo header
Summary
In the Linux kernel, the following vulnerability has been resolved: libbpf: Fix accessing BTF.ext core_relo header Update btf_ext_parse_info() to ensure the core_relo header is present before reading its fields. This avoids a potential buffer read overflow reported by the OSS Fuzz project.
