Understanding the CVE-2025-48060 jq Vulnerability
The core of this security issue lies in a function within jq's codebase called jq_fuzz_execute. A stack buffer overflow occurs when a program writes more data to a buffer located on the stack than what was allocated to hold it.
This can corrupt data, crash the program, and, in sophisticated attacks, allow an attacker to execute arbitrary code.
Vulnerability Type: Stack-based Buffer Overflow

Official CVSS Severity Scores and Analysis
The Common Vulnerability Scoring System (CVSS) provides a standardized method for assessing severity. The scores for CVE-2025-48060 vary slightly between SUSE and the National Vulnerability Database (NVD), reflecting different environmental assumptions.
SUSE Assessment:
CVSS v4.0 Score: 6.9 (Medium) - AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N
CVSS v3.1 Score: 5.3 (Medium) - AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L
Interpretation (v3.1): The attack is local (AV:L), requires low complexity and no privileges, but user interaction is needed (UI:R). It leads to partial compromises of confidentiality, integrity, and availability.*
NVD Assessment:
CVSS v4.0 Score: 7.7 (High) - AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/...
CVSS v3.1 Score: 7.5 (High) - AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Interpretation (v3.1): The NVD scores it higher, assessing it as a network-based attack (AV:N) with no user interaction required, leading to a High impact on Availability (A:H), meaning a successful attack could cause a denial-of-service condition.*

Step-by-Step Patch Installation Instructions
To mitigate the CVE-2025-48060 vulnerability, applying the provided security patch is imperative. SUSE offers multiple methods for applying updates, ensuring flexibility for different deployment scenarios.
General Method (Recommended):
Use the SUSE-recommended tools like YaST online_update or the zypper patch command for a comprehensive system update.
Product-Specific Commands:
For administrators seeking to apply only this specific update, execute the corresponding command for your product:
openSUSE Leap 15.6:
zypper in -t patch openSUSE-SLE-15.6-2025-2915=1SUSE Linux Enterprise Micro 5.3 / Micro for Rancher 5.3:
zypper in -t patch SUSE-SLE-Micro-5.3-2025-2915=1SUSE Linux Enterprise Micro 5.4 / Micro for Rancher 5.4:
zypper in -t patch SUSE-SLE-Micro-5.4-2025-2915=1SUSE Linux Enterprise Micro 5.5:
zypper in -t patch SUSE-SLE-Micro-5.5-2025-2915=1Basesystem Module 15-SP6:
zypper in -t patch SUSE-SLE-Module-Basesystem-15-SP6-2025-2915=1
(Commands for other affected products follow a similar pattern and are listed in the original bulletin.)
Best Practices for Enterprise Security Patching
Beyond applying this single patch, a proactive strategy is key. Organizations should:
Subscribe to Security Feeds: Follow official sources like the SUSE Security Announcement mailing list.
Implement a Staging Workflow: Test all patches in a non-production environment before broad deployment.
Automate Patch Management: Use tools like SUSE Manager or automated scripts to ensure timely updates across large server fleets.
Conduct Regular Audits: Schedule periodic vulnerability scans to identify unpatched systems.
Frequently Asked Questions (FAQ)
Q1: What is jq, and why is it important?
A: jq is a lightweight and powerful command-line JSON processor. It is ubiquitously used in shell scripting for parsing and manipulating JSON data returned from APIs, configuration files, and data streams, making it a critical tool in modern DevOps and cloud-native workflows.
Q2: Can this vulnerability be exploited remotely?
A: The scoring depends on the source. SUSE scores it assuming local access (AV:L), while the NVD assesses it as potentially exploitable over a network (AV:N). The safest assumption is to treat it as a credible threat and patch immediately, especially for systems exposed to untrusted data inputs.
Q3: What is the primary risk if I don't apply this update?
A: The primary risk is a denial-of-service (DoS) attack, where a specially crafted input to the jq command could cause it to crash. In worst-case scenarios, a stack buffer overflow can potentially be leveraged to execute arbitrary code, compromising the system.
Q4: Where can I find the official references for this CVE?
A: Always refer to primary sources for verification:
Official CVE Page: https://www.suse.com/security/cve/CVE-2025-48060.html
SUSE Bug Report: https://bugzilla.suse.com/show_bug.cgi?id=1244116
Conclusion: The CVE-2025-48060 vulnerability in jq is a clear reminder of the shared responsibility in open-source security. While rated as Moderate, its presence in a fundamental tool underscores the need for vigilant patch management.
By following the detailed instructions provided, administrators can effectively neutralize this threat and maintain the security posture of their critical SUSE Linux environments. Review your systems today and prioritize this essential update.
