Mt8189 Firmware
Monthly
Out-of-bounds write in MediaTek's 'vdec' hardware video-decoder path allows remote escalation of privilege on a broad set of affected MediaTek SoCs - including MT6768, MT6833, MT8186, MT8195 and MT6877 - when a victim opens or plays attacker-controlled media that reaches the vulnerable decode routine. Exploitation requires no additional execution privileges or authentication (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, base 8.8) but does require user interaction, since the crafted stream must actually be rendered by the decoder; no public exploit code and no confirmed active exploitation were identified at time of analysis, and the risk is best characterised as a credible, above-average-priority mobile vulnerability rather than an emergency. MediaTek has assigned patch ID ALPS11383899 (issue MSV-9614) and published guidance in its October 2026 product security bulletin.
Local privilege escalation in MediaTek NeuroPilot on affected chipsets (MT8781, MT8189, MT6993, MT8793, MT8910, MT8668, MT8188, MT6881, MT8875) allows an attacker with local code execution to trigger an out-of-bounds write in the APU/AI driver, potentially gaining high-integrity code execution with no user interaction, though no additional privileges are needed once that local app context exists. Vendor patch ALPS11249062 is available; no public exploit identified at time of analysis. It is a high-priority patch target for affected MediaTek-based devices but is not remotely reachable, limiting its scope to privilege escalation rather than initial compromise.
Local privilege escalation in MediaTek's NeuroPilot component allows an attacker with an existing foothold on a device to corrupt memory and elevate privileges via an out-of-bounds write caused by a missing bounds check (CWE-787), rated CVSS 8.4 (AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). Affected platforms are devices built on MediaTek chipsets MT8668, MT8875, MT8781, MT8910, MT6881, MT8188, MT8189 and MT6993 that ship an unpatched NeuroPilot build. The flaw is not remotely reachable and requires local code execution (typically a running or installed Android app with no special privileges); no user interaction or elevated permissions are needed once that foothold exists, and no public exploit code was identified at time of analysis.
Local privilege escalation in MediaTek's Video HAL lets an unprivileged app already running on an affected device corrupt a fixed-size stack buffer via crafted input to the video hardware abstraction layer, yielding code execution in the HAL context with high impact to confidentiality, integrity and availability (CVSS 8.4, AV:L/PR:N/UI:N). The flaw stems from a missing bounds check (CWE-121, stack-based buffer overflow) and affects roughly four dozen MediaTek chipsets spanning the MT6xxx, MT8xxx and MT2718 families used in Android phones, tablets, Chromebooks and automotive platforms. No user interaction and no additional execution privileges are required once local code execution exists, but the attack vector is local only - remote exploitation is not indicated and no public exploit code has been identified at time of analysis. MediaTek has assigned patch ID ALPS11375674 (issue MSV-9571), delivered to OEMs through its October 2026 product security bulletin.
Local privilege escalation in MediaTek venc on multiple chipsets allows an attacker who already possesses System-level privileges to escalate to kernel-level code execution via a type confusion that leads to an out-of-bounds write. The vulnerability requires local access and high privileges (PR:H) with no user interaction, and no public exploit has been identified at the time of analysis. This is a post-compromise escalation step, not a remote or initial-access vector.
Local privilege escalation in MediaTek's mtee (MediaTek TEE) allows an attacker who already holds System privilege to exploit a missing bounds check, causing an out-of-bounds write that can elevate privileges on affected MediaTek chipsets. The vulnerability requires local access and high privileges (PR:H) with no user interaction, and affects 25 listed MediaTek chipset models including MT8196, MT6768, MT6769, MT6833, MT6877, MT8186, and MT8188. No public exploit code or active exploitation has been identified at time of analysis.
Local privilege escalation in MediaTek mtee allows a local attacker who already holds Android System privilege to exploit a CWE-843 type confusion and elevate code execution on affected MediaTek chipsets; user interaction is not required. The flaw is local-only (AV:L) and requires high privileges (PR:H), so it cannot be used for initial access or remote compromise and is primarily useful as a chain component after an attacker has already obtained a System-level foothold. MediaTek has published Patch ID ALPS11383899 in its October 2026 bulletin, and no public exploit identified at time of analysis.
Local privilege escalation in MediaTek's vdec (video decoder) component allows an attacker who already holds System privilege on an affected chipset to supply crafted input that triggers a type-confusion-driven out-of-bounds write, corrupting memory and achieving high confidentiality, integrity, and availability impact at a higher privilege level. The issue affects 24 MediaTek SoCs including MT8395, MT6833, MT6789, MT8195, MT6877, MT8189, MT8391, MT8676, MT8678, MT8793, MT8799, MT6855, MT8367, MT8781, MT8196, MT8910, MT8668, MT8188, MT8792, MT6769, MT6768, MT8186, MT8788E, and MT2718, across mobile, tablet, and embedded platforms. Exploitation is local only, requires the System-privilege prerequisite, and needs no user interaction; the CVSS 3.1 base score is 6.7 (MEDIUM) and no public exploit was identified at time of analysis, so the practical risk is a post-compromise escalation primitive rather than a remote entry point.
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.
Local privilege escalation in MediaTek AIDL on affected chipsets is possible via a use-after-free memory corruption, but only after an attacker has already obtained Android System privilege and local access. Successful exploitation requires no user interaction and can yield high confidentiality, integrity, and availability impact within that privileged context. No public exploit identified at time of analysis; the vendor patch ID ALPS11185225 and the October 2026 MediaTek security bulletin address the issue.
Local privilege escalation in the aidl component shipped on a defined set of MediaTek chipsets (MT6899, MT6991, MT8910, MT8781, MT6881, MT8668, MT6989, MT8188, MT6878, MT6993, MT8695, MT8189, MT8696) allows a process that already holds Android System privilege to trigger a use-after-free, corrupt memory, and gain higher-integrity code execution with high confidentiality, integrity, and availability impact. The attack is local (AV:L) and needs no user interaction, but the PR:H prerequisite means it cannot be used for initial access and only functions as a follow-on escalation from an already-compromised privileged context. At time of analysis there is no confirmed active exploitation (not in CISA KEV) and no public exploit identified at time of analysis; EPSS data was not supplied for this CVE. MediaTek has published a fix under Patch ID ALPS11242428 in its October 2026 Product Security Bulletin.
A missing permission check in the MediaTek AIDL (Android Interface Definition Language) component allows an attacker who already holds the Android System privilege to escalate to higher privileges locally, with no user interaction required. The expected impact is high across confidentiality, integrity, and availability (CVSS 3.1 base 6.7, AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H), but the local-only vector and the PR:H precondition mean an ordinary unprivileged app cannot trigger it directly - it is only useful as a second-stage step in an existing exploit chain or for already-privileged malware. There is no public exploit identified at time of analysis and no confirmed active exploitation (CISA KEV); this is a moderate, defense-in-depth issue rather than a top-tier emergency.
Local privilege escalation in the MediaTek display component lets a process that already holds System privilege trigger an out-of-bounds write in a display-path buffer, corrupting memory and potentially escalating to higher-level code execution with high impact to confidentiality, integrity, and availability. The defect is a missing bounds check (CWE-787) reachable without user interaction and with low attack complexity, but only from an existing System-privileged, on-device context (CVSS 3.1 6.7 Medium, AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H), so it functions as a second-stage escalation primitive rather than an initial-access or remote vector. Affected hardware spans a broad set of MediaTek chipsets including MT6991, MT6993, MT2718, MT8168-class MT8668/MT8678, MT8171, MT8188, MT8189, MT8196, MT8793, and MT8126; MediaTek has issued Patch ID ALPS11292777 (issue MSV-9195) and no public exploit code has been identified at time of analysis.
Local privilege escalation in the battery component shipped with a wide range of MediaTek chipsets (including MT6765, MT6768, MT6853, MT6893, MT6991, MT8186, MT8188 and MT8196) allows an attacker who already holds System privilege to trigger an out-of-bounds write through a missing bounds check, yielding high impact to confidentiality, integrity and availability. No user interaction is required once System access is held, and the flaw is reachable in default configurations of the listed chipsets, making it a post-compromise escalation rather than an initial foothold; the CVSS 6.7 score is dominated by the PR:H prerequisite. A vendor patch is available under MediaTek's October 2026 Product Security Bulletin (patch ID ALPS11276677, issue MSV-9217), and no public exploit code or confirmed active exploitation has been identified at time of analysis.
