CVE-2017-18307

Local information disclosure

Published Nov 26, 2024 · Updated Nov 26, 2024

Information exposure in Qualcomm Snapdragon SD 450, SD 625, SD 820, SD 820A, SD 835, SD 845, and SD 850 allows local users to disclose data. The vendor identifies the kernel and audio playback as the affected context but has not published the faulty operation or exposed data. Exploitation requires local execution during audio playback, and the published narrative establishes only unspecified information disclosure.
