Description

In camera middleware, there is a possible escalation of privilege due to double free. 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: ALPS11134622; Issue ID: MSV-8894.

  "executiveSummary": "A memory management vulnerability, specifically a double free condition, has been identified within the camera middleware component.\nThis flaw permits an escalation of privilege, allowing an attacker who has already compromised the system to elevate their operational status.\nThe vulnerability affects camera middleware and poses a significant risk to system integrity and security posture.\nExploitation does not require user interaction, though it is contingent upon the attacker already possessing System-level privilege within the environment.\nThe identified issue is tracked under Issue ID MSV-8894 and Patch ID ALPS11134622.",
  "technicalDetails": "The vulnerability originates from improper memory lifecycle management within the camera middleware's heap allocation routines. Specifically, the middleware logic fails to properly track the status of dynamic memory pointers, leading to a double free condition. A double free occurs when the free() function is called more than once on the same memory address without an intermediate allocation. This state corrupts the memory allocator's internal structures, such as the heap's free list or chunk metadata.\nIn a typical execution flow, the camera middleware performs operations involving the allocation and subsequent deallocation of memory buffers for image data processing. Due to a logical error in the resource management path, the application attempts to deallocate a pointer that has already been returned to the heap manager. This triggers a heap corruption event, which can be manipulated by an attacker to overwrite arbitrary memory locations or hijack the control flow of the execution process.\nBecause the vulnerability exists in a core middleware component, a successful exploit allows for the manipulation of system memory at high-privilege levels. Since the attacker must have already obtained System privilege to interact with the underlying middleware mechanisms, this vulnerability facilitates an escalation or stabilization of access within the kernel or privileged system space. The absence of a requirement for user interaction suggests that the exploitation path is automated and predictable once the attacker has established an initial foothold with elevated permissions.\nThe exploitation mechanism involves targeting the metadata of the heap management system. By inducing the double free, an attacker can influence the allocator to return an already allocated memory block as part of a subsequent memory request. By carefully crafting the contents of this block, the attacker can overwrite sensitive function pointers or return addresses stored on the stack or in the heap. This enables the redirection of the program's execution to malicious payloads, effectively cementing the attacker's control over the camera-related system operations or the broader system environment. The persistence of this vulnerability within the camera middleware stack represents a critical failure in secure development practices regarding pointer management and resource lifecycle enforcement."
