CVE-2019-10603

Memory corruption via stale IPv6 route reference

Published Mar 5, 2020 · Updated Aug 4, 2024

Use-after-free in Qualcomm Snapdragon HLOS Data on listed chipsets allows local users to corrupt memory via raw IPv6 traffic. The network stack retains or dereferences freed state when the real device interface goes down and a route lookup occurs during transmission of a raw IPv6 message. Local low-privileged access is required; Qualcomm has not disclosed whether exploitation ends in a crash, code execution, or another outcome.
