CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's handling of the common information length in the ieee80211 MLE (Mesh Link Establishment) protocol, specifically in the ieee80211_mle_common_size() and ieee80211_mle_size_ok() functions. This oversight allows for potential exploitation through malformed MLE messages, which could lead to denial of service or unauthorized access within wireless networks. Organizations utilizing Linux-based systems with wireless capabilities should prioritize addressing this vulnerability to mitigate risks associated with MLE communications.
Original NVD 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.
