CVE-2019-14131Network attack vector

Memory corruption via malformed WLAN measurement requests

Published Apr 16, 2020 · Updated Aug 5, 2024

Out-of-bounds write in Qualcomm Snapdragon WLAN firmware allows remote attackers to corrupt memory with malformed radio-measurement requests. The station's WLAN radio-measurement handler improperly validates an array index while processing multiple invalid RRM requests from an access point, causing a write beyond the destination buffer. Exploitation requires a malicious or impersonated access point within wireless range; Qualcomm has not disclosed whether the corruption causes a crash or code execution.
