Local memory corruption via unchecked channel-length loop
Published Mar 5, 2020 · Updated Aug 5, 2024
Buffer overflow in Qualcomm Snapdragon WLAN firmware allows local users to corrupt memory through an oversized channel length. The firmware uses the unbounded channel-length value as a loop limit, allowing iterations beyond the intended buffer boundary. Local low-privileged access is required; Qualcomm reports memory corruption but does not disclose the input interface or a more specific outcome.
