Local privilege escalation via cameraisp out-of-bounds write
Published Feb 2, 2026 · Updated Feb 2, 2026
Out-of-bounds write in the MediaTek chipset cameraisp component allows local users with System privilege to escalate privileges. The component writes beyond an intended buffer because it omits a required bounds check, but MediaTek has not disclosed the buffer or entry point. Exploitation requires prior System privilege and no user interaction; the resulting privilege level and precise corruption consequence remain undisclosed.
