# adsp: integer overflow lets a system-level process write out of bounds

## From the sources

In adsp, there is a possible out of bounds write due to an integer overflow. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: ALPS11431442; Issue ID: MSV-9924.
