Overview

In a world where cybersecurity has become a significant concern for individuals and businesses alike, keeping track of vulnerabilities and assessing their potential impact is of paramount importance. One such vulnerability recently identified is CVE-2025-20668, a critical flaw in the Secure Copy Protocol (scp), which could potentially lead to local privilege escalation. This vulnerability affects all users of scp, a widely used method of securely transferring files between a local and a remote host. The severity of this flaw cannot be overstated, given the potential consequences if exploited.

Vulnerability Summary

CVE ID: CVE-2025-20668
Severity: Critical, CVSS score of 7.8
Attack Vector: Local
Privileges Required: System
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

scp | All versions prior to patch ALPS09625562

How the Exploit Works

The exploit works by taking advantage of an out of bounds write vulnerability due to a missing bounds check within the scp implementation. An attacker, who has already obtained the System privilege, can use this flaw to write data beyond the allocated memory area. This could potentially overwrite other important data and lead to unexpected behavior, including privilege escalation and, in worst cases, a system compromise.

Conceptual Example Code

Here’s a conceptual example of how this vulnerability might be exploited. This pseudocode simulates the scenario of an out-of-bounds write:

# Attacker already has System privileges
$ whoami
system
# Attempt to copy a crafted file using scp
$ scp crafted_file user@target:/path/to/destination
# The crafted_file triggers an out of bounds write in the scp process on the target system

In this example, `crafted_file` is a specially designed file that, when processed by scp, causes it to write data beyond its allocated memory space. Please note that this is a simplified representation of the exploit and the actual exploit would likely involve more sophisticated techniques.

Mitigation Guidance

To mitigate this vulnerability, users are advised to apply the vendor patch identified as ALPS09625562. In scenarios where applying the patch is not immediately feasible, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) is recommended as a temporary mitigation measure. However, these measures do not entirely eliminate the risk, but they can significantly reduce the likelihood of a successful exploit. Users are strongly encouraged to apply the patch as soon as possible to ensure maximum protection.

Impact: System compromise, potential data leakage

Affected Products

Product | Affected Versions

SOLIDWORKS Desktop | 2025
SOLIDWORKS eDrawings | Associated with SOLIDWORKS Desktop 2025

How the Exploit Works

The vulnerability resides in the eDrawings component’s SLDPRT file reading procedure. When a specially crafted SLDPRT file is opened, it triggers a Use-After-Free condition. This condition occurs when an object in memory is used after it has been released, leading to either a system crash or, in more severe cases, the execution of arbitrary code. In this case, an attacker could exploit the vulnerability to execute arbitrary code, potentially gaining control of the system or leading to data leakage.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability could be exploited. A malicious actor creates a specially crafted SLDPRT file containing arbitrary code. The user then opens this file in SOLIDWORKS eDrawings. The malicious code is executed, leading to potential system compromise.

$ echo "arbitrary_code" > malicious.sldprt
$ file malicious.sldprt
malicious.sldprt: SOLIDWORKS eDrawings document, version 2025

This example is vastly simplified and for illustrative purposes only. In reality, the crafting of a malicious SLDPRT file would involve many more complex steps.

Mitigation Guidance

The best way to mitigate the risk associated with CVE-2025-1884 is to apply the vendor-provided patch immediately. Until the patch can be applied, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. It’s also recommended to avoid opening SLDPRT files from unknown sources.

Overview

CVE-2025-1883 is a serious security vulnerability discovered in SOLIDWORKS eDrawings, affecting the Desktop 2025 release. This vulnerability resides in the OBJ file reading procedure and could lead to potentially catastrophic consequences if exploited. It is a type of Out-Of-Bounds Write vulnerability, a common but dangerous class of vulnerabilities that can lead to arbitrary code execution.
This vulnerability matters because SOLIDWORKS is a widely-used 3D CAD (computer-aided design) program, and eDrawings is a popular viewer and editor for SOLIDWORKS and other CAD files. An attacker exploiting this vulnerability could potentially compromise a system or leak sensitive data, impacting businesses and individuals alike.

Vulnerability Summary

CVE ID: CVE-2025-1883
Severity: High (7.8 CVSS v3)
Attack Vector: Local
Privileges Required: Low
User Interaction: Required
Impact: System compromise, data leakage

Affected Products

Product | Affected Versions

SOLIDWORKS eDrawings | Desktop 2025

How the Exploit Works

The exploit involves the manipulation of OBJ files, a standard 3D object format often used in 3D graphics and CAD. In the Desktop 2025 release of SOLIDWORKS eDrawings, the code handling the reading of OBJ files contains an out-of-bounds write vulnerability.
An attacker can craft a malicious OBJ file that, when opened in eDrawings, overflows the buffer allocated for the file’s data. This overflow can overwrite memory locations outside the intended bounds, potentially allowing the attacker to execute arbitrary code.

Conceptual Example Code

An example of a malicious OBJ file might look something like this:

v 1.000000 1.000000 1.000000
v 1.000000 1.000000 -1.000000
... (millions of lines) ...
v -1.000000 -1.000000 -1.000000

This is a vastly simplified representation, but the basic idea is that the file contains far more vertex data (`v`) than the program expects, leading to a buffer overflow.
Users and system administrators are advised to apply the vendor’s patch to mitigate this vulnerability. In the absence of a patch, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could serve as temporary mitigation, although this is less ideal.

Arm 5th Gen GPU Architecture Kernel Driver | r41p0 through r49p3, r50p0 through r53p0

How the Exploit Works

The Use After Free vulnerability occurs when the GPU kernel drivers mishandle the memory allocation and deallocation, allowing a local non-privileged user process to re-use the memory space that has already been freed. This could allow the attacker to insert malicious code or manipulate data in volatile memory, potentially leading to unauthorized access, data corruption or system crashes.

Conceptual Example Code

Below is a simplified example of how this vulnerability might be exploited. This pseudocode illustrates a malicious process attempting to access and manipulate freed memory:

# Pseudocode illustrating the exploit
def exploit():
allocate_memory()  # Allocates memory
free_memory()  # Frees allocated memory
use_freed_memory()  # Attempts to reuse freed memory

The actual exploitation would be much more complex and would require intimate knowledge of the specific GPU kernel driver’s memory management implementation. Nonetheless, this pseudocode should give an idea of the general exploitation process.

Mitigation Guidance

To mitigate this vulnerability, it is recommended to apply the vendor patch as soon as it’s available. In the meantime, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as temporary mitigation. These tools can help detect and block suspicious activities that might be indicative of an attempt to exploit this vulnerability. Regular system monitoring and prompt patch application are key to maintaining robust cybersecurity.

Overview

The focus of our discussion in this blog post is CVE-2025-0072, a critical vulnerability that affects Arm Ltd GPU Kernel Drivers. It is a Use After Free vulnerability that allows a local non-privileged user process to perform improper GPU memory processing operations and gain unauthorized access to already freed memory. This vulnerability can potentially lead to system compromise or data leakage, posing a high risk to any system utilizing the affected drivers. In the era of cybersecurity threats, understanding this vulnerability, its possible impacts, and mitigation measures is of utmost importance for cybersecurity professionals and system administrators alike.

Vulnerability Summary

CVE ID: CVE-2025-0072
Severity: High (7.8 CVSS Score)
Attack Vector: Local
Privileges Required: Low (Non-privileged)
User Interaction: Required
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

Valhall GPU Kernel Driver | r29p0 through r49p3, r50p0 through r53p0
Arm 5th Gen GPU Architecture Kernel Driver | r41p0 through r49p3, r50p0 through r53p0

How the Exploit Works

In the context of a Use After Free vulnerability, an attacker exploits the improper processing of GPU memory operations by accessing memory that has already been freed. This allows the attacker to read from, write to, or execute code from memory locations that should not be accessible. As a result, the attacker can gain control over the system or leak sensitive data.

Conceptual Example Code

While the exact code to exploit this vulnerability is beyond the scope of this article, a conceptual example might look something like this:

void exploit() {
char* ptr = malloc(100);   // Allocate 100 bytes
free(ptr);                 // Free the allocated memory
strcpy(ptr, "malicious_payload");  // Write to the freed memory
execute(ptr);              // Execute the malicious payload
}

In this conceptual example, memory is allocated and then freed. Following that, the same memory space is used to store a malicious payload, which is then executed. This demonstrates the essence of a Use After Free vulnerability, where the freed memory is not properly managed and can be accessed post-deallocation.

Impact: Code execution, Denial of Service, Escalation of Privileges, Information Disclosure, Data Tampering

Affected Products

Product | Affected Versions

NVIDIA GPU Display Driver for Linux | All Versions

How the Exploit Works

The exploit involves an unprivileged attacker exploiting this vulnerability to escalate permissions without requiring user interaction. This is possible due to improper isolation of system activities within NVIDIA GPU Display Driver for Linux. Once the attacker has escalated permissions, they have the potential to execute code, cause a denial of service, escalate further privileges, disclose information, and tamper with data.

Conceptual Example Code

Here’s a simple conceptual example of how this vulnerability might be exploited. Please note that this is a hypothetical scenario and does not represent an actual exploit.

# Attacker gains low-level access to the system
$ ssh attacker@target.example.com
# Attacker identifies the NVIDIA GPU Display Driver for Linux
$ lsmod | grep nvidia
# Attacker uses a crafted payload to exploit the vulnerability
$ echo "malicious_payload" > /dev/nvidia0

In this example, the attacker first gains low-level access to the system. They then identify the NVIDIA GPU Display Driver for Linux and use a specifically crafted payload to exploit the vulnerability. This leads to permission escalation, after which the attacker is free to undertake malicious activities such as data tampering or information disclosure.
To protect against this vulnerability, affected organizations are advised to apply vendor patches or use Web Application Firewalls/Intrusion Detection Systems as temporary mitigation.
