Local memory corruption via oversized TPC table
Published Mar 4, 2024 · Updated Aug 12, 2024
Stack-based buffer overflow in Qualcomm Snapdragon WLAN HAL firmware allows local users to corrupt memory through crafted FTM TPC input. FTM TPC processing writes a target-power table beyond a stack buffer because the table size is not constrained to the destination bounds. The path is local and requires no prior privileges; successful corruption can compromise firmware confidentiality, integrity, and availability.

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.
