  "description": "In the Linux kernel, the following vulnerability has been resolved:  libbpf: Reject non-exclusive metadata maps in the signed loader  The loader verifies map-\u003Esha against the metadata hash in its instructions. map-\u003Esha is calculated when BPF_OBJ_GET_INFO_BY_FD is called on the frozen map.  While the map is frozen, the /signed loader/ must also ensure the map is exclusive, as, without exclusivity (which a hostile host could just omit when loading the loader), another BPF program with map access can mutate the contents afterwards, so the check passes on stale data.  With the extra check as part of the signed loader, it now refuses to move on with map-\u003Esha validation if the host set it up wrongly.",
