  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211_hwsim: drop short frames\n\nWhile technically some control frames like ACK are shorter and\nend after Address 1, such frames shouldn't be forwarded through\nwmediumd or similar userspace, so require the full 3-address\nheader to avoid accessing invalid memory if shorter frames are\npassed in.",
