A malformed\nframe can advertise an IE length larger than the available data, causing\nthe parser to increment its pointer beyond the buffer end. This results\nin out-of-bounds reads or, depending on the pattern, an infinite loop.\n\nFix by validating that (offset + 2 + len) does not exceed the limit\nbefore accepting the IE or advancing to the next element.\n\nThis prevents OOB reads and ensures the parser terminates safely on\nmalformed frames.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":48.4,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
