CVE-2023-35655

Local privilege escalation via Darwinn heap over-read

Published Oct 11, 2023 · Updated Sep 18, 2024

A heap-buffer over-read in Google Android's Darwinn component allows local users with System execution privileges to elevate access. CanConvertPadV2Op in darwinn_mlir_converter_aidl.cc reads beyond a heap buffer when checking whether a PadV2 operation can be converted. The gate is local System execution, no user interaction is needed, and the record does not identify the resulting higher privilege.
