GHSA-Q3WQ-4HWF-24Q4

Vulnerability from github – Published: 2022-05-24 19:05 – Updated: 2023-03-15 00:30
VLAI
Details

An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the tftp_input() function and could occur while processing a udp packet that is smaller than the size of the 'tftp_t' structure. This issue may lead to out-of-bounds read access or indirect host memory disclosure to the guest. The highest threat from this vulnerability is to data confidentiality. This flaw affects libslirp versions prior to 4.6.0.

Vulnerability from github – Published: 2026-06-24 18:32 – Updated: 2026-07-14 21:31
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

fwctl: Fix class init ordering to avoid NULL pointer dereference on device removal

CXL is linked before fwctl in drivers/Makefile. Both use module_init, socxl_pci_driver_init()runs first. Whencxl_pci_probe()callsfwctl_register()and thendevice_add(), fwctl_class is not yet registered because fwctl_init() hasn't run, causingclass_to_subsys()` to return NULL and skip knode_class initialization.

On device removal, class_to_subsys() returns non-NULL, and device_del() calls klist_del() on the uninitialized knode, triggering a NULL pointer dereference.

VLAI
Details

An issue was discovered in PHOENIX CONTACT PC Worx through 1.86, PC Worx Express through 1.86, and Config+ through 1.86. A manipulated PC Worx or Config+ project file could lead to an Uninitialized Pointer and remote code execution. The attacker needs to get access to an original PC Worx or Config+ project file to be able to manipulate it. After manipulation, the attacker needs to exchange the original file with the manipulated one on the application programming workstation.

Vulnerability from github – Published: 2022-05-17 00:14 – Updated: 2022-05-17 00:14
VLAI
Details

An issue was discovered in Adobe Acrobat and Reader: 2017.012.20098 and earlier versions, 2017.011.30066 and earlier versions, 2015.006.30355 and earlier versions, and 11.0.22 and earlier versions. This vulnerability is due to a computation that accesses a pointer that has not been initialized; the computation occurs during internal AST thread manipulation. In this case, a computation defines a read from an unexpected memory location. Therefore, an attacker might be able to read sensitive portions of memory.

GHSA-QPXP-M556-4MCR

Vulnerability from github – Published: 2025-10-09 18:30 – Updated: 2025-10-09 18:30
VLAI
Details

An Access of Uninitialized Pointer vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved with BGP sharding configured allows an attacker triggering indirect next-hop updates, along with timing outside the attacker's control, to cause rpd to crash and restart, leading to a Denial of Service (DoS).

With BGP sharding enabled, triggering route resolution of an indirect next-hop (e.g., an IGP route change over which a BGP route gets resolved), may cause rpd to crash and restart. An attacker causing continuous IGP route churn, resulting in repeated route re-resolution, will increase the likelihood of triggering this issue, leading to a potentially extended DoS condition.

This issue affects:

Junos OS:

  • all versions before 21.4R3-S6, 
  • from 22.1 before 22.1R3-S6, 
  • from 22.2 before 22.2R3-S3, 
  • from 22.3 before 22.3R3-S3, 
  • from 22.4 before 22.4R3, 
  • from 23.2 before 23.2R2; 

Junos OS Evolved: 

  • all versions before 22.3R3-S3-EVO, 
  • from 22.4 before 22.4R3-EVO, 
  • from 23.2 before 23.2R2-EVO.

Versions before Junos OS 21.3R1 and Junos OS Evolved 21.3R1-EVO are unaffected by this issue.

Summary
Reference binding to nullptr in map operations

Impact

An attacker can cause undefined behavior via binding a reference to null pointer in tf.raw_ops.Map* and tf.raw_ops.OrderedMap* operations:

import tensorflow as tf

tf.raw_ops.MapPeek(
  key=tf.constant([8],dtype=tf.int64),
  indices=[],
  dtypes=[tf.int32],
  capacity=8,
  memory_limit=128)

The implementation has a check in place to ensure that indices is in ascending order, but does not check that indices is not empty.

Patches

We have patched the issue in GitHub commit 532f5c5a547126c634fefd43bbad1dc6417678ac.

The fix will be included in TensorFlow 2.6.0. We will also cherrypick this commit on TensorFlow 2.5.1, TensorFlow 2.4.3, and TensorFlow 2.3.4, as these are also affected and still in supported range.
