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."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/wireless/core.c"],"versions":[{"version":"2ab658f9ce218ae93b3d2db2b3fe68bfefb81196","lessThan":"1305f8b925fe92edf5fec183588dfc7db719180b","status":"affected","versionType":"git"},{"version":"2ab658f9ce218ae93b3d2db2b3fe68bfefb81196","lessThan":"4cbb2360f4d8c29e67bc7a8bf6ba0ae096583923","status":"affected","versionType":"git"},{"version":"2ab658f9ce218ae93b3d2db2b3fe68bfefb81196","lessThan":"7187d145d9042b037e4f10538f70cf95e380219f","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/wireless/core.c"],"versions":[{"version":"2.6.32","status":"affected"},{"version":"0","lessThan":"2.6.32","status":"unaffected","versionType":"semver"},{"version":"6.12.111","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.32","versionEndExcluding":"6.12.111"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.32","versionEndExcluding":"6.18.53"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.32","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/1305f8b925fe92edf5fec183588dfc7db719180b"},{"url":"https://git.kernel.org/stable/c/4cbb2360f4d8c29e67bc7a8bf6ba0ae096583923"},{"url":"https://git.kernel.org/stable/c/7187d145d9042b037e4f10538f70cf95e380219f"}],"title":"wifi: cfg80211: reject duplicate wiphy cipher suite entries","x_generator":{"engine":"bippy-1.2.0"}}}}
