  "title": "linux: In the Linux kernel, the following vulnerability has been resolved:  wifi: mac80211: consume only present negotiated...",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  wifi: mac80211: consume only present negotiated TTLM maps  ieee80211_tid_to_link_map_size_ok() validates negotiated TTLM elements against the number of link-map entries indicated by link_map_presence. ieee80211_parse_neg_ttlm() must consume the same layout.  The parser advanced its cursor for every TID, including TIDs whose presence bit is clear and therefore have no map bytes in the element. A sparse map can then make a later present TID read past the validated element.  The bad bytes land in neg_ttlm-\u003E{up,down}link[tid] but are gated by valid_links before being applied to driver state, so a peer cannot turn the read into a policy change.  Under KUnit \u002B KASAN with an exact-sized element allocation the OOB read is reported as a slab-out-of-bounds; whether the same trigger fires under the production RX path depends on surrounding allocator state.  Advance the cursor only when the current TID has a map present.",
