Description

In meta, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege, if an attacker has physical access to the device, with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS11049530 / ALPS11480843; Issue ID: MSV-7935.

  "executiveSummary": "A critical out-of-bounds (OOB) write vulnerability has been identified within the 'meta' component, stemming from a lack of necessary input validation and bounds checking.\nThis flaw allows an attacker with physical access to the target device to corrupt memory, potentially leading to local escalation of privilege (EoP).\nThe vulnerability does not require user interaction or pre-existing execution privileges, making it a significant security risk for devices where physical contact is achievable.\nThe absence of bounds checking permits writing data outside the allocated memory buffer, which can be leveraged to overwrite sensitive memory structures, potentially altering control flow or escalating system permissions.\nThe vulnerability is tracked under Issue ID: MSV-7935 and is addressed by patches ALPS11049530 and ALPS11480843.",
  "technicalDetails": "The root cause of this vulnerability is an improper implementation of memory management within the 'meta' component, specifically concerning a missing bounds check before a memory write operation.\nWhen the component processes data, it fails to verify that the target address resides within the assigned memory segment boundaries. This oversight permits the application to perform a write operation beyond the allocated buffer, resulting in a heap or stack-based out-of-bounds memory corruption.\nExploitation is initiated through physical access to the device. An attacker can supply a specially crafted payload—likely via a debug interface, peripheral port, or hardware-level interaction—that causes the vulnerable function to perform an out-of-bounds write.\nThe attack flow proceeds as follows: First, the attacker triggers the vulnerable function within the 'meta' component by providing input that exceeds expected size constraints. Second, due to the missing bounds check, the system processes this input and writes it to an unauthorized memory location. Third, by carefully controlling the contents of the overflow, the attacker overwrites adjacent memory, such as function pointers, return addresses, or object metadata.\nBy overwriting critical kernel structures or process control blocks, an attacker can achieve local escalation of privilege. This allows the execution of code with higher-than-normal permissions, potentially granting the attacker root or kernel-level access. Because the exploitation occurs at the component level without requiring prior authentication or user interaction, the impact on system integrity and confidentiality is severe.\nThe post-exploitation impact includes persistent compromise of the local environment, bypass of security boundaries, and unauthorized access to protected system resources. The lack of validation acts as a primitive that an attacker can chain to achieve arbitrary code execution or local privilege escalation."
