Remote privilege escalation via WPS bounds check
Published Dec 25, 2021 · Updated Aug 4, 2024
Out-of-bounds write in MediaTek wifi driver 7.4.0.0 allows remote attackers to escalate privileges via WPS from a proximal network. The wifi driver omits a bounds check while processing WPS protocol input, permitting a crafted nearby wireless exchange to overwrite memory. Exploitation requires WPS use and user interaction; the resulting impact is privilege escalation, with no evidence of confidentiality or availability impact beyond the elevated execution context.
