CVE-2026-21901

CVE-2026-21901 describes a NULL pointer dereference in Juniper Networks Junos OS and Junos OS Evolved mgd (management daemon) when a local, high-privileged user configures or deactivates a specific 'system services ssh' parameter. The vulnerability causes an mgd crash and restart, enabling a sust...

USN-8526-1 libheif vulnerabilities

Xianrui Dong discovered that libheif had an out-of-bounds read in its HEIF sequence track parser. An attacker could possibly use this issue to cause a denial of service or obtain sensitive information. This issue only affected Ubuntu 26.04 LTS. CVE-2026-47254 Junyi Liu discovered that libheif had...

USN-8526-1: libheif vulnerabilities

PYSEC-2026-3365 Missing validation results in undefined behavior in `SparseTensorDenseAdd

Impact The implementation of tf.rawops.SparseTensorDenseAdd does not fully validate the input arguments: python import tensorflow as tf aindices = tf.constant0, shape=17, 2, dtype=tf.int64 avalues = tf.constant, shape=0, dtype=tf.float32 ashape = tf.constant6, 12, shape=2, dtype=tf.int64 b =...

PYSEC-2026-3135 Null-dereference in Tensorflow

Impact The implementation of GetInitOp is vulnerable to a crash caused by dereferencing a null pointer: cc const auto& initopsigit = metagraphdef.signaturedef.findkSavedModelInitOpSignatureKey; if initopsigit != sigdefmap.end initopname = initopsigit-second.outputs...

PYSEC-2026-3153 Null-dereference in Tensorflow

Impact When decoding a tensor from protobuf, TensorFlow might do a null-dereference if attributes of some mutable arguments to some operations are missing from the proto. This is guarded by a DCHECK: cc const auto attr = attrs.Findarg-s; DCHECKattr != nullptr; if attr-valuecase == AttrValue::kLis...

PYSEC-2026-3223 Undefined behavior in `SparseTensorSliceDataset`

Impact The implementation of SparseTensorSliceDataset has an undefined behavior: under certain condition it can be made to dereference a nullptr value: python import tensorflow as tf import numpy as np tf.rawops.SparseTensorSliceDataset indices=, values=, denseshape=1,1 The 3 input arguments...

PYSEC-2026-3173 Null pointer dereference in TensorFlow

Impact When building an XLA compilation cache, if default settings are used, TensorFlow triggers a null pointer dereference: cc string allowedgpus = flr-configproto-gpuoptions.visibledevicelist; In the default scenario, all devices are allowed, so flr-configproto is nullptr. Patches We have patch...

PYSEC-2026-3094 Null pointer dereference in TensorFlow

Impact The implementation of QuantizedMaxPool has an undefined behavior where user controlled inputs can trigger a reference binding to null pointer. python import tensorflow as tf tf.rawops.QuantizedMaxPool input = tf.constant4, dtype=tf.quint8, mininput = , maxinput = 1, ksize = 1, 1, 1, 1,...

PYSEC-2026-3154 Null pointer dereference in Grappler's `IsConstant`

Impact Under certain scenarios, Grappler component of TensorFlow can trigger a null pointer dereference. There are 2 places where this can occur, for the same malicious alteration of a SavedModel file fixing the first one would trigger the same dereference in the second place: First, during...
