Until a patch is available, restrict access to systems with affected chipsets to trusted users only, as exploitation requires existing System privilege.

Description

CVE-2026-20575 is a type confusion vulnerability in MediaTek chipsets that can cause memory corruption via use-after-free. Exploitation does not require user interaction but requires the attacker to already have System privilege. This flaw could lead to local privilege escalation on affected MediaTek chipset models.
