CISA-ADP AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

CISA-ADP CWE-787

In the Linux kernel, the following vulnerability has been resolved:

libbpf: Use OPTS_SET() macro in bpf_xdp_query()

When the feature_flags and xdp_zc_max_segs fields were added to the libbpf
bpf_xdp_query_opts, the code writing them did not use the OPTS_SET() macro.
This causes libbpf to write to those fields unconditionally, which means
that programs compiled against an older version of libbpf (with a smaller
size of the bpf_xdp_query_opts struct) will have its stack corrupted by
libbpf writi
