Mediatek Chipset

Local privilege escalation in the Modem component across 80+ MediaTek chipsets allows an attacker already holding System-level access to bypass permission enforcement (CWE-280) and escalate further within the device. The vulnerability is confirmed by MediaTek in their July 2026 Product Security Bulletin (Patch ID: MOLY01716533, Issue ID: MSV-6309) and affects a broad swath of chipsets spanning low-end to flagship tiers. No user interaction is required for exploitation, but the prerequisite of System-level access significantly constrains the realistic attack surface. No public exploit code or CISA KEV listing has been identified at time of analysis.

Heap buffer overflow in the Telephony subsystem of MediaTek chipsets enables local privilege escalation on affected Android devices, delivering full confidentiality, integrity, and availability impact. Twenty-two specific MediaTek SoC variants are confirmed affected, spanning the MT6xxx and MT8xxx mid-range and budget families. No public exploit has been identified at time of analysis; MediaTek has issued patch ALPS11006447 via their July 2026 security bulletin, but exploitation requires a pre-existing System-level privilege on the device, making this a chaining vulnerability rather than a standalone entry vector.

Out-of-bounds write in MediaTek modem firmware allows a network-adjacent attacker controlling a rogue cellular base station to remotely crash affected User Equipment (UE), resulting in denial of service. Thirty-three distinct MediaTek chipsets - spanning flagship mobile SoCs (MT6991, MT6989, MT6985) to tablet and IoT chipsets (MT8795T, MT8893) - contain the vulnerable modem component identified under Patch IDs MOLY01267281 and MOLY01318201. No public exploit code has been identified at time of analysis, and the attack is non-trivial due to the requirement for attacker-controlled cellular infrastructure, but the sheer deployment scale of affected chipsets across Android devices makes the aggregate exposure significant.

Information disclosure in MediaTek modem firmware across 67+ chipset models enables a network-adjacent attacker operating a rogue cellular base station to extract sensitive data from a victim's User Equipment (UE) without any privileges or user interaction. The root cause is improper input validation (CWE-288) in the modem baseband stack, allowing a fake cell tower to elicit confidential data from connected devices. No active exploitation has been confirmed by CISA KEV, and SSVC assessment rates exploitation as 'none' at time of analysis, though the architecture of the attack closely resembles IMSI-catcher and stingray-type tradecraft used in targeted surveillance operations.

Remote denial-of-service in MediaTek modem firmware across 80+ chipset families allows an attacker operating a rogue cellular base station to crash affected devices by sending malformed input the modem fails to validate. The vulnerability (CWE-288) requires no privileges on the target device and no user interaction - a device that autonomously connects to the attacker's false base station is sufficient. No public exploit code has been identified at time of analysis, and SSVC classifies exploitation status as none, though the widespread chipset deployment across Android handsets and IoT hardware makes the affected attack surface extremely broad.

Remote privilege escalation in the baseband modem firmware of dozens of MediaTek chipsets allows an attacker operating a rogue base station to corrupt modem memory via a missing bounds check (out-of-bounds write, CWE-787). Once a target UE camps on the attacker-controlled cell, exploitation requires no user interaction and no pre-existing privileges, potentially yielding privilege escalation within the modem subsystem. Tracked in MediaTek's July 2026 Product Security Bulletin (Patch ID MOLY01402160); there is no public exploit identified at time of analysis and it is not listed in CISA KEV.

Remote denial of service in the MediaTek Modem firmware component affects approximately 60 chipset models via a null pointer dereference triggered when a target device connects to a rogue cellular base station. An attacker controlling a fake eNodeB or gNodeB can transmit crafted modem protocol messages that cause improper input validation to fail, crashing the modem and stripping affected devices of cellular connectivity. No public exploit has been identified at time of analysis, and CISA SSVC rates current exploitation status as none, indicating this remains a theoretical but technically feasible threat for well-resourced actors.

Out-of-bounds write in the MediaTek WLAN STA (Station mode) driver enables local denial of service across six MediaTek Wi-Fi chipset families, confirmed by MediaTek in their June 2026 Product Security Bulletin. A low-privileged local user can crash the system without any user interaction by triggering the missing bounds check in the driver, exploiting CWE-787 memory corruption. No public exploit code has been identified and this vulnerability is not listed in the CISA KEV catalog at time of analysis.

Local privilege escalation in MediaTek GenieZone (trusted execution environment) allows an attacker who has already gained System-level privileges on an affected device to write out-of-bounds memory and escalate further on the chipset. The flaw affects a broad range of MediaTek chipsets used in mobile and embedded devices, with no public exploit identified at time of analysis. CVSS is 7.8 (High) reflecting the high integrity, confidentiality, and availability impact despite the local attack vector.

Local privilege escalation in MediaTek's GenieZone hypervisor component affects 36 distinct chipsets via a race condition-induced out-of-bounds write. An attacker who has already obtained System-level privilege on an affected Android device can exploit the TOCTOU flaw to escalate further - likely to kernel or hypervisor-level execution - achieving full confidentiality, integrity, and availability impact. No public exploit has been identified at time of analysis, and no KEV listing exists; however, the wide chipset footprint spanning flagship to budget SoCs significantly broadens the potential attack surface.

Local privilege escalation in MediaTek's geniezone hypervisor component affects 36 distinct chipsets spanning budget to flagship tiers. An attacker who has already achieved System-level privilege can trigger an out-of-bounds write caused by a missing bounds check, escalating further - likely into kernel or hypervisor trust boundaries - with full confidentiality, integrity, and availability impact. No public exploit identified at time of analysis, and this is not listed in the CISA KEV catalog; however, the post-compromise escalation path makes this relevant to threat actors performing multi-stage device compromise on Android-based MediaTek hardware.

Heap buffer overflow in the MediaTek WLAN access point driver allows adjacent-network attackers with low-privilege user execution to corrupt memory and achieve remote code execution without user interaction. The flaw affects multiple MediaTek Wi-Fi chipsets commonly embedded in routers and access points (MT7615, MT7915, MT7916, MT7981, MT7986, MT7990, MT7992, MT7993, MT6890). No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
