Memory disclosure via unchecked request-buffer length
Published Sep 9, 2021 · Updated Aug 3, 2024
An out-of-bounds read in Qualcomm Snapdragon products allows local users with low privileges to read memory via a crafted request buffer. The affected request handler performs no request-buffer length check before reading, permitting access past the buffer boundary. Local low-privileged access is required; Qualcomm has not disclosed the exact request interface or memory contents exposed.
