Description

In battery, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: ALPS11276677; Issue ID: MSV-9217.

  "executiveSummary": "A critical out-of-bounds (OOB) write vulnerability has been identified within the battery management subsystem of the affected product. This security flaw stems from insufficient input validation during data processing, allowing for memory corruption.\nThe vulnerability poses a significant risk to system integrity. Although exploitation requires the adversary to have already attained System-level privileges, the flaw enables further escalation of privilege or potential code execution within the kernel context. No user interaction is required for a successful exploit, making this a high-severity concern for system stability and security architecture.\nThe issue, tracked under Issue ID MSV-9217 and Patch ID ALPS11276677, underscores a failure in proper bounds checking when handling battery-related data structures. Once the attacker has established the necessary prerequisite privilege, they can leverage this memory corruption to manipulate system state or bypass security controls. Mitigation involves applying the provided vendor patch to enforce strictly validated boundaries during memory access operations.",
  "technicalDetails": "The root cause of this vulnerability is a missing bounds check in the battery management driver. Specifically, the software fails to validate the size or offset of input data before performing a write operation to a memory buffer. This absence of validation allows an attacker to write data beyond the allocated buffer boundaries, resulting in an OOB write condition.\nThe exploitation path requires the attacker to first secure System-level privileges on the target device. In the context of kernel-mode components, once this privilege level is attained, the attacker can interface directly with the battery driver's input/output control (IOCTL) handlers or shared memory regions. By providing a crafted input that exceeds the expected buffer size, the attacker triggers the vulnerability during the write operation.\nThe attack flow proceeds as follows: 1) The attacker initiates a request to the battery component. 2) The driver receives the payload without verifying the constraints of the destination memory buffer. 3) The memory write instruction executes, overwriting adjacent memory locations in the kernel space. 4) The overwritten data can be utilized to corrupt sensitive kernel objects, function pointers, or data structures that govern security policy enforcement.\nBecause the vulnerability occurs within a privileged driver context, successful exploitation can lead to local escalation of privilege (EoP). By carefully crafting the OOB write, an attacker can redirect execution flow or overwrite critical kernel data to grant unauthorized access or persistence. The lack of required user interaction facilitates silent exploitation by any malicious actor who has already bypassed initial system access controls.\nThis vulnerability highlights the critical importance of secure memory management in device drivers, particularly those that handle hardware communication or state management. The failure to implement strict bounds checking effectively allows a privileged adversary to undermine the kernel's memory safety guarantees. The impact is substantial, as it allows for the manipulation of the operating system's internal state, potentially leading to a complete compromise of the system's security posture."
