Memory corruption via oversized WiFi display inputs
Published Nov 4, 2024 · Updated Nov 16, 2024
Memory corruption in Qualcomm chipset firmware allows local users with high privileges to corrupt memory through WiFi display APIs. The APIs process large random inputs without adequate validation, although Qualcomm has not disclosed the exact function or memory operation involved. The high-privilege local gate limits reachability, and the vendor has not disclosed whether exploitation causes a crash or code execution.

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.
