CVE-2019-14083Network attack vector

Integer underflow via malformed extended SSI length

Published Mar 5, 2020 · Updated Aug 5, 2024

Improper length validation in Qualcomm Snapdragon WLAN firmware allows remote attackers to trigger an integer underflow through an SDF frame. The Service Descriptor Extended Attribute parser accepts an incorrect extended-SSI attribute length without validating it before performing its length calculation. Exposure requires receipt of a crafted WLAN SDF frame; Qualcomm has not published the resulting memory operation or concrete consequence.
