CVE-2023-54247

CVE-2023-54247: In the Linux kernel, the BPF code silences a WARN_ON_ONCE in btf_type_id_size() when handling DECL_TAG by adding DECL_TAG to the btf_type_nosize set, causing btf_type_id_size() to return NULL earlier. This fixes a spurious warning without indicating a correctness issue; no exploit...

CVE-2022-50855
