CWE ids for CVE-2023-3725

  • The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
    Assigned by: vulnerabilities@zephyrproject.org (Secondary)
  • A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
    Assigned by: vulnerabilities@zephyrproject.org (Secondary)
  • The product writes data past the end, or before the beginning, of the intended buffer.
