In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
wifi: cfg80211: reject duplicate wiphy cipher suite entries<\/p>\n
Duplicate entries in wiphy->cipher_suites do not describe any
\nadditional capability, but cfg80211 currently accepts them and leaves
\nindividual consumers to deal with them.<\/p>\n
One 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.<\/p>\n
Reject 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.<\/p>\n","protected":false},"excerpt":{"rendered":"
