Local privilege escalation via dpe use-after-free
Published Jan 6, 2026 · Updated Jan 6, 2026
Use-after-free memory corruption in dpe on MediaTek MT6899, MT6991, and MT8793 chipsets allows local users to escalate privileges. MediaTek has not published the affected dpe operation or the object whose lifetime is mishandled; the available record identifies only access to freed memory. Exploitation requires prior System privilege, needs no user interaction, and can corrupt memory with confidentiality, integrity, and availability impact.
