Mt8390 Firmware
Monthly
Local privilege escalation in MediaTek's meta component affects numerous MediaTek chipsets (including MT6789, MT6895, MT6985, MT8195, and others listed in EUVD-2026-92196) and allows an attacker with physical access to the device to trigger an out-of-bounds write due to a missing bounds check, achieving high confidentiality and integrity impact. No authentication, existing execution privileges, or user interaction are required once physical access is obtained. No public exploit has been identified at time of analysis; the physical access prerequisite limits remote exploitation and confines realistic abuse to scenarios such as lost or stolen devices, border inspection, or supply-chain tampering.
Use-after-free memory corruption in MediaTek's apusys driver allows a local attacker who has already obtained Android System privilege (uid system) to escalate to kernel-level code execution on affected devices, with no user interaction required once that foothold exists. The flaw affects firmware running on a broad set of MediaTek SoCs - including MT6897, MT6899, MT6989, MT6991, MT8196, MT8678 and the other MT-series chipsets listed in MediaTek's October 2026 bulletin - and is addressed by Patch ID ALPS11076799 (Issue ID MSV-8143). Because the CVSS vector carries PR:H and AV:L, this is a second-stage privilege-escalation link that presupposes a prior System-level compromise rather than a standalone remotely reachable bug; no public exploit code or confirmed active exploitation was identified at time of analysis.
