Title
zstd-jni 1.5.5-6 through 1.5.7-13 Out-of-Bounds Read via Negative Offset
Summary
zstd-jni versions 1.5.5-6 through 1.5.7-13 contain an out-of-bounds read vulnerability in Zstd.getFrameContentSize that fails to validate negative srcPosition arguments. Attackers can supply negative offset values that bypass bounds checks and reach the native frame-header parser, causing out-of-bounds memory reads that lead to information disclosure or JVM crashes.

CVE-2026-88054 (GCVE-0-2026-88054)

Title
Tesseract: Denial of service via empty-stack dereference in Plumbing/Series at model load
Summary
Tesseract is an open source OCR engine. In version 5.5.3 and earlier, Plumbing::DeSerialize in src/lstm/plumbing.cpp rejects excessively large network stacks but accepts a zero-length stack for NT_SERIES, NT_PARALLEL, or NT_REVERSED layers in a crafted .traineddata model. During LSTMRecognizer initialization in src/lstm/lstmrecognizer.cpp, CacheXScaleFactor(XScaleFactor()) reaches Series::CacheXScaleFactor in src/lstm/series.cpp, which dereferences stack_[0] on the empty vector and invokes a virtual method through an invalid Network pointer. This causes a deterministic crash and denial of service at model load. No fixed release is available as of this review.

Title
Tesseract: Heap out-of-bounds write/read in FullyConnected::Forward via layer/weight-matrix dimension mismatch
Summary
Tesseract is an open source OCR engine. In version 5.5.3 and earlier, FullyConnected::DeSerialize in src/lstm/fullyconnected.cpp does not validate the deserialized layer scalars ni_ and no_ against the weight-matrix dimensions. During FullyConnected::Forward, MatrixDotVector in src/lstm/weightmatrix.cpp writes w.dim1() results into temp_line, which is sized from no_, and reads w.dim2() minus one inputs from curr_input, which is sized from ni_. A crafted .traineddata NT_SOFTMAX layer can therefore use inconsistent dimensions to cause a heap out-of-bounds write and read on the default LSTM engine, resulting in heap corruption, a crash, information disclosure, or potentially controlled corruption. No fixed release is available as of this review.

Title
ESP32-audioI2S 3.4.4 through 4.0.0 Heap-based Out-of-Bounds Read via Shadowed Length Parameter in read_ID3_Header
Summary
ESP32-audioI2S versions 3.4.4 through 4.0.0 contain a heap-based out-of-bounds read vulnerability in the read_ID3_Header function due to a shadowed length parameter in ID3 synchronized-lyrics processing. Attackers can craft malicious MP3 files or HTTP audio streams with oversized frame size declarations to read past allocated buffer boundaries, causing device crashes or exposing adjacent heap memory.

CVE-2026-87875 (GCVE-0-2026-87875)

Vulnerability from cvelistv5 – Published: 2026-09-09 16:06 – Updated: 2026-09-10 10:38

Title
Cups: openprinting cups: heap out-of-bounds read in cupsutf32toutf8() via missing source-length bound
Summary
The cupsUTF32ToUTF8() function in CUPS's cups/transcode.c lacks a source-length bound and can read past the end of the source buffer, resulting in a heap out-of-bounds read. This is reachable via SNMP supply-description parsing in backend/snmp-supplies.c with attacker-controlled content.

CVE-2026-87824 (GCVE-0-2026-87824)

Vulnerability from cvelistv5 – Published: 2026-09-09 14:32 – Updated: 2026-09-09 14:32

Title
zstd-jni 1.3.3-1 through 1.5.7-13 Out-of-Bounds Read via Zstd.trainFromBufferDirect
Summary
zstd-jni before 1.5.7-14 fails to validate the samples buffer capacity in Zstd.trainFromBufferDirect, allowing attackers to read past buffer boundaries by supplying oversized per-sample lengths. Attackers can trigger out-of-bounds memory access by providing crafted sample length arrays that cause the native implementation to walk past the buffer allocation, resulting in JVM termination.

Title
zstd-jni 1.2.0 through 1.5.7-13 Out-of-Bounds Read via ZstdDictCompress
Summary
zstd-jni versions before 1.5.7-14 fail to validate offset and length parameters in the ZstdDictCompress constructor, allowing out-of-bounds memory reads. Attackers can supply untrusted offset or length values to read native heap memory into the compression dictionary, typically causing JVM crashes.

CVE-2026-86714 (GCVE-0-2026-86714)

Title
PX4 Autopilot through 1.17.0 Stack Buffer Over-read via netman
Summary
PX4 Autopilot through 1.17.0 contains a stack buffer over-read vulnerability in the netman system command that fails to validate interface name length. Attackers can supply interface names of 74 bytes or more via the -i option to read beyond buffer boundaries, leaking stack memory to console output or writing it into persistent network configuration files.

Implementation

Strategy: Input Validation

  • Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
  • When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
  • Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
  • To reduce the likelihood of introducing an out-of-bounds read, ensure that you validate and ensure correct calculations for any length argument, buffer size calculation, or offset. Be especially careful of relying on a sentinel (i.e. special character such as NUL) in untrusted inputs.
Mitigation
Architecture and Design

Strategy: Language Selection

Use a language that provides appropriate memory abstractions.

CAPEC-540: Overread Buffers

An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.
