Local privilege escalation via unchecked GScan length
Published Mar 10, 2025 · Updated Sep 4, 2025
Out-of-bounds write in Android's dhd4381 SoC driver allows local users to escalate privileges through a crafted GScan event. The wl_notify_gscan_event function in wl_cfgscan.c writes event-derived data without first validating its length against the destination bounds. Exploitation requires existing low-privileged local execution on an affected Pixel Watch, needs no user interaction, and can grant higher privileges.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
