Mt8371 Firmware
Monthly
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.
