Overview CVE-2025-20770 is a critical vulnerability affecting MediaTek display drivers. This vulnerability is classified as a use-after-free, potentially leading to memory corruption. A successful exploit could allow a malicious actor who has already obtained System privileges to escalate those privileges further on the local system. Crucially, user interaction is not required to trigger this vulnerability. Technical Details The vulnerability resides within the display component. Specifically, a use-after-free condition occurs, meaning that a memory location is accessed after it has already been freed. This can lead to unpredictable behavior, including program crashes or the execution of arbitrary code. The specific code…

Overview CVE-2025-20769 is a security vulnerability affecting MediaTek display drivers. This vulnerability allows a malicious actor, who has already obtained System privilege, to potentially escalate their privileges further due to a missing bounds check that leads to an out-of-bounds write. User interaction is not required to exploit this vulnerability. Technical Details The vulnerability resides within the display driver code. Specifically, a missing bounds check allows an attacker to write data outside the allocated memory region. This out-of-bounds write can overwrite critical system data, potentially leading to arbitrary code execution with elevated privileges. The root cause is a failure to validate…

Overview CVE-2025-20768 is a security vulnerability discovered in MediaTek display drivers. This flaw could potentially allow a malicious actor with existing System privileges to escalate their privileges further on the affected device. The vulnerability stems from a missing bounds check in the display driver, leading to a potential out-of-bounds read operation. No user interaction is required to exploit this vulnerability once the attacker possesses System privileges. Technical Details The root cause of CVE-2025-20768 lies in a missing bounds check within the display driver code. During display processing, the driver attempts to access memory locations. Without proper validation of the input…

Overview CVE-2025-20767 is a vulnerability affecting display components, characterized by an integer overflow that can lead to an out-of-bounds write. This vulnerability can be exploited by a malicious actor who has already obtained System privilege, potentially leading to local escalation of privilege. No user interaction is required for successful exploitation. Technical Details The root cause of CVE-2025-20767 lies in an integer overflow within the display sub-system. Specifically, when handling certain display parameters, the system fails to properly validate the size of an operation, leading to an integer overflow. This overflow results in the allocation of a buffer smaller than required,…

Overview CVE-2025-20766 is a security vulnerability affecting the display component of a system. It is characterized by a memory corruption issue stemming from improper input validation. Successfully exploiting this vulnerability could allow a malicious actor, who has already obtained System privilege, to achieve local escalation of privilege. Importantly, user interaction is not required for exploitation. The vulnerability is identified by the Patch ID ALPS10196993 and Issue ID MSV-4820. Technical Details The root cause of CVE-2025-20766 lies in insufficient validation of input data processed by the display component. This lack of validation allows a specially crafted input to overwrite memory, leading…

Overview CVE-2025-20765 describes a vulnerability found in the aee daemon. This vulnerability is characterized by a race condition that can potentially lead to a system crash. Exploitation requires a malicious actor to have already obtained System privileges. Successfully exploiting this vulnerability can result in a local denial of service (DoS). The vulnerability is addressed by patch ALPS10190802 and tracked internally as Issue ID MSV-4833. Technical Details The specific technical details of the race condition within the aee daemon are not fully disclosed, however, the nature of race conditions makes them notoriously difficult to debug and exploit. A race condition occurs…

Overview CVE-2025-20764 is a security vulnerability discovered in SMI (System Management Interface). This out-of-bounds write vulnerability could potentially allow a malicious actor who has already obtained System privilege to escalate their privileges further within the system. Exploitation requires the attacker to have System privileges already and does not require user interaction. Technical Details The root cause of CVE-2025-20764 lies in a missing bounds check within the SMI code. This oversight allows for a write operation to occur outside the intended memory boundaries, potentially overwriting critical system data or code. The specific vulnerable area is addressed by Patch ID ALPS10259774 and…

Overview CVE-2025-20763 describes a potential security vulnerability within MediaTek’s mmdvfs component. This vulnerability stems from a missing bounds check that can lead to an out-of-bounds write. If successfully exploited by a malicious actor who has already gained System privilege, it could result in a local escalation of privilege. No user interaction is required for exploitation. The issue is identified by MediaTek as Patch ID ALPS10267218 and Issue ID MSV-5032. Technical Details The vulnerability resides within the mmdvfs component and is triggered by a missing bounds check during a write operation. This oversight allows an attacker, having already achieved System privilege,…

Overview CVE-2025-20759 is a security vulnerability identified in MediaTek modem firmware. It involves an out-of-bounds read vulnerability which could be exploited to trigger a remote denial-of-service (DoS) condition. The vulnerability stems from a missing bounds check within the modem’s processing logic. If a user equipment (UE), such as a mobile phone, connects to a rogue base station controlled by an attacker, the attacker can potentially exploit this vulnerability without needing any user interaction or additional execution privileges on the device. A patch has been released by MediaTek to address this issue. Technical Details The root cause of CVE-2025-20759 is a…

Overview CVE-2025-20758 is a newly discovered vulnerability affecting MediaTek modem firmware. This vulnerability allows a remote attacker to cause a system crash, leading to a denial-of-service (DoS) condition. The vulnerability is triggered by an uncaught exception within the modem’s software. Exploitation is possible without user interaction and requires no elevated privileges, posing a significant risk to affected devices. Technical Details The root cause of CVE-2025-20758 lies in the modem firmware’s handling of specific network conditions. Specifically, an uncaught exception can occur when a User Equipment (UE) connects to a rogue or malicious base station controlled by an attacker. The vulnerability…
