CWE-787
Weakness Allowed-with-ReviewOut-of-bounds Write
Abstraction: Base · Status: Draft
The product writes data past the end, or before the beginning, of the intended buffer.
Dimensions
- Behavior-Type: Write
- Resource-Type: Memory Buffer
- Resource-Property: Out-of-bounds
Mapping guidance
This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities. However, closer examination is required.
While this CWE is allowed for mapping, it has more specific children that might be a better fit. Carefully read both the name and description to ensure that this mapping is appropriate. Consider the root cause errors that have led to the out-of-bounds write by examining "CanFollow" relationships for this entry.
Relationships and members
Modes of introduction
Detection methods
Automated Static Analysis
This weakness can often be detected using automated static analysis tools. Many modern tools use data flow analysis or constraint-based techniques to minimize the number of false positives.
Automated static analysis generally does not account for environmental considerations when reporting out-of-bounds memory operations. This can make it difficult for users to determine which warnings should be investigated first. For example, an analysis tool might report buffer overflows that originate from command line arguments in a program that is not expected to run with setuid or other special privileges.
Effectiveness: High
Detection techniques for buffer-related errors are more mature than for most other weakness types.
Automated Dynamic Analysis
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.
Automated Dynamic Analysis
Use tools that are integrated during compilation to insert runtime error-checking mechanisms related to memory safety errors, such as AddressSanitizer (ASan) for C/C++ [REF-1518].
Effectiveness: Moderate
Crafted inputs are necessary to reach the code containing the error, such as generated by fuzzers. Also, these tools may reduce performance, and they only report the error condition - not the original mistake that led to the error.

Vulnerability from github – Published: 2025-04-01 18:30 – Updated: 2026-10-30 15:32In the Linux kernel, the following vulnerability has been resolved:
nvme-tcp: fix potential memory corruption in nvme_tcp_recv_pdu()
nvme_tcp_recv_pdu() doesn't check the validity of the header length. When header digests are enabled, a target might send a packet with an invalid header length (e.g. 255), causing nvme_tcp_verify_hdgst() to access memory outside the allocated area and cause memory corruptions by overwriting it with the calculated digest.
Fix this by rejecting packets with an unexpected header length.

GHSA-P534-C2V5-6CH3
Vulnerability from github – Published: 2024-08-26 12:31 – Updated: 2024-08-27 18:31In the Linux kernel, the following vulnerability has been resolved:
bnxt_en : Fix memory out-of-bounds in bnxt_fill_hw_rss_tbl()
A recent commit has modified the code in __bnxt_reserve_rings() to set the default RSS indirection table to default only when the number of RX rings is changing. While this works for newer firmware that requires RX ring reservations, it causes the regression on older firmware not requiring RX ring resrvations (BNXT_NEW_RM() returns false).
With older firmware, RX ring reservations are not required and so hw_resc->resv_rx_rings is not always set to the proper value. The comparison:
if (old_rx_rings != bp->hw_resc.resv_rx_rings)
in __bnxt_reserve_rings() may be false even when the RX rings are changing. This will cause __bnxt_reserve_rings() to skip setting the default RSS indirection table to default to match the current number of RX rings. This may later cause bnxt_fill_hw_rss_tbl() to use an out-of-range index.
We already have bnxt_check_rss_tbl_no_rmgr() to handle exactly this scenario. We just need to move it up in bnxt_need_reserve_rings() to be called unconditionally when using older firmware. Without the fix, if the TX rings are changing, we'll skip the bnxt_check_rss_tbl_no_rmgr() call and __bnxt_reserve_rings() may also skip the bnxt_set_dflt_rss_indir_tbl() call for the reason explained in the last paragraph. Without setting the default RSS indirection table to default, it causes the regression:

Mitigation MIT-3
Strategy: Language Selection
- Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, many languages that perform their own memory management, such as Java and Perl, are not subject to buffer overflows. Other languages, such as Ada and C#, typically provide overflow protection, but the protection can be disabled by the programmer.
- Be wary that a language's interface to native code may still be subject to overflows, even if the language itself is theoretically safe.
Mitigation MIT-4.1
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- Examples include the Safe C String Library (SafeStr) by Messier and Viega [REF-57], and the Strsafe.h library from Microsoft [REF-56]. These libraries provide safer versions of overflow-prone string-handling functions.
Mitigation MIT-10
Strategy: Environment Hardening
- Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index checking.
- D3-SFCV (Stack Frame Canary Validation) from D3FEND [REF-1334] discusses canary-based detection in detail.
Mitigation MIT-9
- Consider adhering to the following rules when allocating and managing an application's memory:
- Double check that the buffer is as large as specified.
- When using functions that accept a number of bytes to copy, such as strncpy(), be aware that if the destination buffer size is equal to the source buffer size, it may not NULL-terminate the string.
- Check buffer boundaries if accessing the buffer in a loop and make sure there is no danger of writing past the allocated space.
- If necessary, truncate all input strings to a reasonable length before passing them to the copy and concatenation functions.
Mitigation MIT-11
Strategy: Environment Hardening
- Run or compile the software using features or extensions that randomly arrange the positions of a program's executable and libraries in memory. Because this makes the addresses unpredictable, it can prevent an attacker from reliably jumping to exploitable code.
- Examples include Address Space Layout Randomization (ASLR) [REF-58] [REF-60] and Position-Independent Executables (PIE) [REF-64]. Imported modules may be similarly realigned if their default memory addresses conflict with other modules, in a process known as "rebasing" (for Windows) and "prelinking" (for Linux) [REF-1332] using randomly generated addresses. ASLR for libraries cannot be used in conjunction with prelink since it would require relocating the libraries at run-time, defeating the whole purpose of prelinking.
- For more information on these techniques see D3-SAOR (Segment Address Offset Randomization) from D3FEND [REF-1335].
Mitigation MIT-12
Strategy: Environment Hardening
- Use a CPU and operating system that offers Data Execution Protection (using hardware NX or XD bits) or the equivalent techniques that simulate this feature in software, such as PaX [REF-60] [REF-61]. These techniques ensure that any instruction executed is exclusively at a memory address that is part of the code segment.
- For more information on these techniques see D3-PSEP (Process Segment Execution Prevention) from D3FEND [REF-1336].
Mitigation MIT-13
Replace unbounded copy functions with analogous functions that support length arguments, such as strcpy with strncpy. Create these if they are not available.
