  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: cfg80211: reject duplicate wiphy cipher suite entries\n\nDuplicate entries in wiphy-\u003ecipher_suites do not describe any\nadditional capability, but cfg80211 currently accepts them and leaves\nindividual consumers to deal with them.\n\nOne such consumer is the WEXT compatibility code, which appends a WEP\nkey length for each WEP cipher entry it sees. Repeated WEP entries can\ntherefore overflow the fixed iw_range::encoding_size array returned by\nSIOCGIWRANGE.\n\nReject duplicate cipher suite entries in wiphy_register() instead.\nThis keeps the cipher suite invariant in one place and makes malformed\nwiphy descriptions fail early with -EINVAL, rather than relying on a\nsingle cfg80211 user to handle duplicates correctly.",
