CVE-2021-41200

TensorFlow is an open source platform for machine learning. In affected versions if tf.summary.createfilewriter is called with non-scalar arguments code crashes due to a CHECK-fail. The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1, TensorFlow...

CVE-2022-23564

Tensorflow is an Open Source Machine Learning Framework. When decoding a resource handle tensor from protobuf, a TensorFlow process can encounter cases where a CHECK assertion is invalidated based on user controlled arguments. This allows attackers to cause denial of services in TensorFlow...

CVE-2022-35991

TensorFlow is an open source platform for machine learning. When TensorListScatter and TensorListScatterV2 receive an elementshape of a rank greater than one, they give a CHECK fail that can trigger a denial of service attack. We have patched the issue in GitHub commit...

CVE-2022-35992

TensorFlow is an open source platform for machine learning. When TensorListFromTensor receives an elementshape of a rank greater than one, it gives a CHECK fail that can trigger a denial of service attack. We have patched the issue in GitHub commit 3db59a042a38f4338aa207922fa2f476e000a6ee. The fi...

CVE-2023-25676

TensorFlow is an open source machine learning platform. When running versions prior to 2.12.0 and 2.11.1 with XLA, tf.rawops.ParallelConcat segfaults with a nullptr dereference when given a parameter shape with rank that is not greater than zero. A fix is available in TensorFlow 2.12.0 and 2.11.1...

CVE-2021-41206

TensorFlow is an open source platform for machine learning. In affected versions several TensorFlow operations are missing validation for the shapes of the tensor arguments involved in the call. Depending on the API, this can result in undefined behavior and segfault or CHECK-fail related crashes...

CVE-2022-23594

Tensorflow is an Open Source Machine Learning Framework. The TFG dialect of TensorFlow MLIR makes several assumptions about the incoming GraphDef before converting it to the MLIR-based dialect. If an attacker changes the SavedModel format on disk to invalidate these assumptions and the GraphDef i...

CVE-2022-23560

Tensorflow is an Open Source Machine Learning Framework. An attacker can craft a TFLite model that would allow limited reads and writes outside of arrays in TFLite. This exploits missing validation in the conversion from sparse tensors to dense tensors. The fix is included in TensorFlow 2.8.0. We...

CVE-2022-23584

Tensorflow is an Open Source Machine Learning Framework. A malicious user can cause a use after free behavior when decoding PNG images. After png::CommonFreeDecode gets called, the values of decode.width and decode.height are in an unspecified state. The fix will be included in TensorFlow 2.8.0. ...

CVE-2022-35939

TensorFlow is an open source platform for machine learning. The ScatterNd function takes an input argument that determines the indices of of the output tensor. An input index greater than the output tensor or less than zero will either write content at the wrong index or trigger a crash. We have...

CVE-2022-35938

TensorFlow is an open source platform for machine learning. The GatherNd function takes arguments that determine the sizes of inputs and outputs. If the inputs given are greater than or equal to the sizes of the outputs, an out-of-bounds memory read or a crash is triggered. This issue has been...

CVE-2025-13628

CVE-2025-13628 affects Tutor LMS – eLearning and online course solution (WordPress) up to version 3.9.3. The vulnerability results from missing capability checks in bulk_action_handler and coupon_permanent_delete, allowing authenticated users with subscriber-level access or higher to delete, acti...

The vulnerability of the LTI13Authenticator function of the JupyterHub jupyterhub-ltiauthenticator, related to cryptographic signature verification errors, allows a perpetrator to execute remote code, thereby enabling them to influence the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the LTI13Authenticator function of the JupyterHub jupyterhub-ltiauthenticator component is related to errors in verifying the cryptographic signature. Exploiting this vulnerability could allow an attacker to influence the confidentiality, integrity, and accessibility of the...

Unified Framework for Qualifying Security Boundary of PUFs against Machine Learning Attacks

Physical Unclonable Functions PUFs serve as lightweight, hardware-intrinsic entropy sources widely deployed in IoT security applications. However, delay-based PUFs are vulnerable to Machine Learning Attacks MLAs, undermining their assumed unclonability. There are no valid metrics for evaluating P...

CVE-2025-14802

The LearnPress – WordPress LMS Plugin for WordPress is vulnerable to unauthorized file deletion in versions up to, and including, 4.3.2.2 via the /wp-json/lp/v1/material/fileid REST API endpoint. This is due to a parameter mismatch between the DELETE operation and authorization check, where the...
