TEE memory disclosure via faulty access denial
Published Mar 10, 2025 · Updated Mar 11, 2025
Out-of-bounds read in Android kernel LDFW allows local users with System privileges to disclose TEE memory without user interaction. A logic error in ppcfw_deny_sec_dram_access in ppcfw.c permits an arbitrary read from TEE memory rather than denying the access. Exploitation requires code executing with System privileges on an affected Pixel device; it exposes protected memory but requires no user interaction.

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?
