CVE-2023-33071

Memory corruption via unauthorized HAb graphics access

Published Dec 5, 2023 · Updated Feb 25, 2026

Improper access control in Qualcomm Snapdragon Automotive OS allows local users to corrupt memory through HAb graphics access. Qualcomm identifies the HAb graphics interface as the locus but has not published the missing authorization check or memory operation that causes corruption. Execution of an untrusted application on an affected Snapdragon Auto chipset is required; the published record defines no resulting behavior beyond memory corruption.
