  "details": "In the Linux kernel, the following vulnerability has been resolved:  wifi: mac80211: count only matching reservations in reserved switch  ieee80211_vif_use_reserved_switch() validates a replacement by counting assigned links on ctx-\u003ereplace_ctx and treating reservations too broadly. A link can still be assigned to the old channel context while holding a reservation that belongs to a different replacement operation.  That can make the current replacement appear complete too early. If another link finalizes first, the function can free the WILL_BE_REPLACED chanctx while the unmatched link and driver still use it, leading to a use-after-free in later beacon generation.  Require an in-place reservation to point at the current replacement context, and require the reserved and assigned contexts to be the matching replacement pair, before counting or moving the link.",
