CWE-125 : Out-of-bounds Read
The product reads data past the end, or before the beginning, of the intended buffer. When an out-of-bounds read occurs, typically the product has already made a separate mistake, such as modifying an index or performing pointer arithmetic that produces an out-of-bounds address. Shorthand for "Out of bounds" read Fuzz testing (fuzzing) is a powerful technique for generating large numbers of diverse inputs - either randomly or algorithmically - and dynamically invoking the code with those inputs. Even with random inputs, it is often capable of generating unexpected results such as crashes, memory corruption, or resource consumption. Fuzzing effectively produces repeatable test cases that clearly indicate bugs, which helps developers to diagnose the issues. Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.) Use a language that provides appropriate memory abstractions. The reference implementation code for a Trusted Platform Module does not implement length checks on data, allowing for an attacker to read 2 bytes past the end of a buffer. Out-of-bounds read in IP stack used in embedded systems, as exploited in the wild per CISA KEV. Chain: "Heartbleed" bug receives an inconsistent length parameter (CWE-130) enabling an out-of-bounds read (CWE-126), returning memory that could include private cryptographic keys and other sensitive data. HTML conversion package has a buffer under-read, allowing a crash Chain: unexpected sign extension (CWE-194) leads to integer overflow (CWE-190), causing an out-of-bounds read (CWE-125) Chain: product does not handle when an input string is not NULL terminated (CWE-170), leading to buffer over-read (CWE-125) or heap-based buffer overflow (CWE-122). Chain: series of floating-point precision errors(CWE-1339) in a web browser rendering engine causes out-of-bounds read(CWE-125), giving access to cross-origin data out-of-bounds read due to improper length check packet with large number of specified elements cause out-of-bounds read. packet with large number of specified elements cause out-of-bounds read. out-of-bounds read, resultant from integer underflow large length value causes out-of-bounds read malformed image causes out-of-bounds read OS kernel trusts userland-supplied length value, allowing reading of sensitive information

CWE-787 : Out-of-bounds Write
The product writes data past the end, or before the beginning, of the intended buffer. At the point when the product writes data to an invalid location, it is likely that a separate weakness already occurred earlier. For example, the product might alter an index, perform incorrect pointer arithmetic, initialize or release memory incorrectly, etc., thus referencing a memory location outside the buffer. Often used to describe the consequences of writing to memory outside the bounds of a buffer, or to memory that is otherwise invalid. This weakness can be detected using dynamic tools and techniques that interact with the software using large test suites with many diverse inputs, such as fuzz testing (fuzzing), robustness testing, and fault injection. The software's operation may slow down, but it should not become unstable, crash, or generate incorrect results. Replace unbounded copy functions with analogous functions that support length arguments, such as strcpy with strncpy. Create these if they are not available. Font rendering library does not properlyhandle assigning a signed short value to an unsignedlong (CWE-195), leading to an integer wraparound(CWE-190), causing too small of a buffer (CWE-131),leading to an out-of-bounds write(CWE-787). The reference implementation code for a Trusted Platform Module does not implement length checks on data, allowing for an attacker to write 2 bytes past the end of a buffer. Chain: insufficient input validation (CWE-20) in browser allows heap corruption (CWE-787), as exploited in the wild per CISA KEV. GPU kernel driver allows memory corruption because a user can obtain read/write access to read-only pages, as exploited in the wild per CISA KEV. Chain: integer truncation (CWE-197) causes small buffer allocation (CWE-131) leading to out-of-bounds write (CWE-787) in kernel pool, as exploited in the wild per CISA KEV. Out-of-bounds write in kernel-mode driver, as exploited in the wild per CISA KEV. Escape from browser sandbox using out-of-bounds write due to incorrect bounds check, as exploited in the wild per CISA KEV. Memory corruption in web browser scripting engine, as exploited in the wild per CISA KEV. chain: mobile phone Bluetooth implementation does not include offset when calculating packet length (CWE-682), leading to out-of-bounds write (CWE-787) Chain: compiler optimization (CWE-733) removes or modifies code used to detect integer overflow (CWE-190), allowing out-of-bounds write (CWE-787). malformed inputs cause accesses of uninitialized or previously-deleted objects, leading to memory corruption chain: -1 value from a function call was intended to indicate an error, but is used as an array index instead. Unchecked length of SSLv2 challenge value leads to buffer underflow. Buffer underflow from a small size value with a large buffer (length parameter inconsistency, CWE-130) Chain: integer signedness error (CWE-195) passes signed comparison, leading to heap overflow (CWE-122) Classic stack-based buffer overflow in media player using a long entry in a playlist Heap-based buffer overflow in media player using a long entry in a playlist
