Local privilege escalation via geniezone use-after-free
Published Jan 6, 2026 · Updated Jan 6, 2026
Use-after-free in MediaTek geniezone on affected Android 15.0 chipsets allows local users with System privilege to elevate privileges. MediaTek identifies memory corruption from reuse of freed memory in geniezone but does not disclose the vulnerable function or object-lifecycle error. Exploitation requires prior System privilege and no user interaction, and successful exploitation compromises confidentiality, integrity, and availability.
