CVE-2020-3613

Kernel memory corruption via mapping double free

Published Jun 22, 2020 · Updated Aug 4, 2024

Double free in Qualcomm Snapdragon DSP services on SM8150 allows local users to corrupt kernel memory through a kernel mapping operation. The mapping path frees the same allocation twice because it lacks a memory-protection mechanism; Qualcomm has not published the responsible function or input sequence. Low-privileged local access is required, and successful exploitation can compromise confidentiality, integrity, and availability within the existing security scope.
