Description

An issue was discovered in camera in Samsung Mobile Processor Exynos 1330, 1380, 1480, 2400, 1580, 2500, 2600, and 1680. In the camera driver, an out-of-bounds array access vulnerability in the error-handling path leads to memory corruption.

  "executiveSummary": "An out-of-bounds (OOB) array access vulnerability exists within the camera driver of specific Samsung Exynos mobile processors, including the 1330, 1380, 1480, 2400, 1580, 2500, 2600, and 1680 models.\nThe vulnerability originates in the driver's error-handling path, where improper boundary validation allows access to memory locations outside the intended array buffer.\nSuccessful exploitation of this flaw can lead to memory corruption, potentially enabling an attacker to achieve arbitrary code execution, privilege escalation, or unauthorized access to sensitive camera-related data.\nThe vulnerability poses a significant security risk to the integrity and confidentiality of the affected mobile devices, as it resides within privileged system-level driver code.\nExploitation typically requires an attacker to possess the ability to interact with the camera driver interface, often through malicious application software or secondary exploit chains that gain local access to the device's driver subsystem.",
  "technicalDetails": "The vulnerability is localized within the error-handling logic of the Samsung camera driver stack. Specifically, when an anomalous condition or hardware error occurs, the driver logic triggers an execution path designed to capture or report the state; however, this path fails to perform adequate bounds checking on an index used to access a internal array structure.\nDuring this fault-handling procedure, the driver retrieves an index value derived from the state of the camera hardware or a previous processing operation. If the index value falls outside the predefined memory boundaries of the array, the processor performs a read or write operation at an unintended memory address. Because the error-handling path is essentially a fallback mechanism, it often operates with elevated system privileges, meaning the memory corruption occurs in a context that may allow for the overwrite of critical kernel data structures or function pointers.\nThe attack flow commences by providing specifically crafted inputs or triggering hardware-level events that force the camera driver to enter its error-handling routine. Once the execution flow is redirected to the vulnerable code path, the lack of input validation allows for an out-of-bounds access. An attacker can manipulate the index value to point to adjacent kernel memory or sensitive driver configuration data.\nIn a successful exploitation scenario, an attacker could overwrite adjacent heap objects or return addresses to gain control over the instruction pointer. By redirecting execution to attacker-controlled shellcode or performing Return-Oriented Programming (ROP), the attacker can elevate their process privileges to those of the camera driver, effectively bypassing the Android security model to gain deep system access.\nThe vulnerability affects Exynos 1330, 1380, 1480, 2400, 1580, 2500, 2600, and 1680. It represents a classic example of improper error handling leading to memory safety violations in low-level drivers. Given that camera drivers often have direct access to hardware buffers and DMA regions, corruption here can be leveraged to compromise not only the camera functionality but the entire device operating system."
