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-2022-50862

CVE-2022-50862 affects the Linux kernel BPF subsystem. The issue arises in creating a function prototype that returns a type referencing decl_tag, as analyzed via bpf/btf.c and related code paths (btf_type_id_size, btf_parse_type_sec, btf_new_fd, bpf_btf_load). The provided traces show a kernel w...
