The brcm80211 component in the Linux kernel through 6.5.10 has a brcmf_cfg80211_detach use-after-free in the device unplugging (disconnect the USB by hotplug) code. For physically proximate attackers with local access, this "could be exploited in a real world scenario." This is related to brcmf_cfg80211_escan_timeout_worker in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c.
