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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/1305f8b925fe92edf5fec183588dfc7db719180b","tags":[]},{"url":"https://git.kernel.org/stable/c/4cbb2360f4d8c29e67bc7a8bf6ba0ae096583923","tags":[]},{"url":"https://git.kernel.org/stable/c/7187d145d9042b037e4f10538f70cf95e380219f","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
