Title
Uninitialized memory access in Eigen types in TensorFlow
Summary
In affected versions of TensorFlow under certain cases a saved model can trigger use of uninitialized values during code execution. This is caused by having tensor buffers be filled with the default value of the type but forgetting to default initialize the quantized floating point types in Eigen. This is fixed in versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2, and 2.4.0.

Title
Memory corruption in Tensorflow
Summary
In Tensorflow before versions 2.2.1 and 2.3.1, the implementation of `dlpack.to_dlpack` can be made to use uninitialized memory resulting in further memory corruption. This is because the pybind11 glue code assumes that the argument is a tensor. However, there is nothing stopping users from passing in a Python object instead of a tensor. The uninitialized memory address is due to a `reinterpret_cast` Since the `PyObject` is a Python object, not a TensorFlow Tensor, the cast to `EagerTensor` fails. The issue is patched in commit 22e07fb204386768e5bcbea563641ea11f96ceb8 and is released in TensorFlow versions 2.2.1, or 2.3.1.

Title
Junos OS: EX, QFX and MX series: Packet Forwarding Engine manager (FXPC) process crashes due to a crafted HTTP packet in a Virtual Chassis configuration
Summary
A certain crafted HTTP packet can trigger an uninitialized function pointer deference vulnerability in the Packet Forwarding Engine manager (fxpc) on all EX, QFX and MX Series devices in a Virtual Chassis configuration. This issue can result in a crash of the fxpc daemon or may potentially lead to remote code execution. This issue only occurs when the crafted packet it destined to the device. Affected releases are Juniper Networks Junos OS: 14.1X53 versions prior to 14.1X53-D47 on EX and QFX Virtual Chassis Platforms; 15.1 versions prior to 15.1R7-S3 all Virtual Chassis Platforms 15.1X53 versions prior to 15.1X53-D50 on EX and QFX Virtual Chassis Platforms.

Summary
Nokogiri affected by libxslt Use of Uninitialized Resource/Use After Free vulnerability
Details
In xsltCopyText in transform.c in libxslt 1.1.33, a pointer variable isn't reset under certain circumstances. If the relevant memory area happened to be freed and reused in a certain way, a bounds check could fail and memory outside a buffer could be written to, or uninitialized data could be disclosed.
Nokogiri prior to version 1.10.5 contains a vulnerable version of libxslt. Nokogiri version 1.10.5 upgrades the dependency to libxslt 1.1.34, which contains a patch for this issue.

Vulnerability from github – Published: 2025-09-22 21:30 – Updated: 2025-09-22 21:30

Details
In the Linux kernel, the following vulnerability has been resolved:
ALSA: firewire-lib: fix uninitialized flag for AV/C deferred transaction
AV/C deferred transaction was supported at a commit 00a7bb81c20f ("ALSA: firewire-lib: Add support for deferred transaction") while 'deferrable' flag can be uninitialized for non-control/notify AV/C transactions. UBSAN reports it:

This commit fixes the bug. The bug has no disadvantage for the non- control/notify AV/C transactions since the flag has an effect for AV/C response with INTERIM (0x0f) status which is not used for the transactions in AV/C general specification.

Mitigation
Implementation
Explicitly initialize the resource before use. If this is performed through an API function or standard procedure, follow all required steps.
Mitigation
Implementation
Pay close attention to complex conditionals that affect initialization, since some branches might not perform the initialization.
Mitigation
Implementation
Avoid race conditions (CWE-362) during initialization routines.
Mitigation
Build and Compilation
Run or compile the product with settings that generate warnings about uninitialized variables or data.
No CAPEC attack patterns related to this CWE.
