CVE-2019-14122

Memory failure via unchecked SKB padding

Published Apr 16, 2020 · Updated Aug 5, 2024

Improper exception handling in Snapdragon Auto and Snapdragon Mobile allows local users to trigger memory failure via crafted SKB padding requests. The SKB path does not correctly handle failure when requested padding cannot be added under low-memory or heavily fragmented conditions. Reaching the condition requires local access to the affected Qualcomm platform; the record does not specify a distinct confidentiality, integrity, or availability outcome beyond memory failure.
