Description

In the Linux kernel, the following vulnerability has been resolved: wifi: ieee80211: validate MLE common info length ieee80211_mle_common_size() uses the first common-info octet as the common information length for all known MLE types. However, ieee80211_mle_size_ok() only validates that octet for Basic, Probe Request, and TDLS MLEs. Reconfiguration MLEs also skipped the length octet when calculating the minimum common size, and Priority Access MLEs skipped validation of the advertised common information length. Account for the Reconfiguration common-info length octet and validate the advertised common information length for all known MLE types. Keep unknown-type handling unchanged. [remove now misleading comment]
