Local information disclosure via variable-time comparisons
Published Jun 2, 2020 · Updated Aug 5, 2024
Timing side channel in Qualcomm Snapdragon QTEE platforms allows local users to infer sensitive data from comparison runtimes. QTEE compares sensitive values with variable-time functions such as memcmp, causing execution time to disclose information about compared values. Exploitation requires local low-privilege execution and repeated timing measurements; the published impact is limited to confidentiality.
