Name of the Vulnerable Software and Affected Versions Android versions Android-13

Description In the parameterToHal function of Effect.cpp, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege in the audio server with System execution privileges needed. User interaction is not needed for exploitation.

Recommendations For Android version Android-13, consider applying a patch that includes a bounds check in the parameterToHal function of Effect.cpp to prevent out of bounds writes. As a temporary workaround, restrict access to the audio server to minimize the risk of exploitation.
