      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211: count only matching reservations in reserved switch\n\nieee80211_vif_use_reserved_switch() validates a replacement by counting\nassigned links on ctx->replace_ctx and treating reservations too\nbroadly. A link can still be assigned to the old channel context while\nholding a reservation that belongs to a different replacement\noperation.\n\nThat can make the current replacement appear complete too early. If\nanother link finalizes first, the function can free the\nWILL_BE_REPLACED chanctx while the unmatched link and driver still use\nit, leading to a use-after-free in later beacon generation.\n\nRequire an in-place reservation to point at the current replacement\ncontext, and require the reserved and assigned contexts to be the\nmatching replacement pair, before counting or moving the link.",
