Information disclosure via underflowed sub-IE length
Published Jul 1, 2024 · Updated Aug 1, 2024
Integer underflow in Qualcomm Snapdragon WLAN host communication allows remote attackers to disclose information via crafted wireless input. During new information-element generation, sub-IE length parsing underflows and applies a wrapped length while processing the element. No authentication or user interaction is required, and exploitation can disclose information or interrupt WLAN service.
