CVE-2025-58364
Public on
Last Modified:
Description
A flaw was found in the CUPS printing system’s ipp_read_io() function, which handles Internet Printing Protocol (IPP) requests. When processing specially crafted printer attribute responses, improper validation can cause a null pointer dereference. This leads to a crash in libcups, potentially disrupting printing services. Since CUPS is widely deployed on Linux systems for printer discovery and management, this issue can cause denial-of-service (DoS) across multiple machines on a local network.
Statement
The Red Hat Product Security team has assessed the severity of this vulnerability as Moderate . The flaw can be remotely exploited within local subnets to crash CUPS services without requiring authentication or user interaction. In cases where machines expose IPP services to the internet, the vulnerability may be exploitable over the network. The root cause is improper deserialization and validation of printer attributes in the ipp_read_io() function, leading to null pointer dereference and denial-of-service.
Mitigation
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.

Common Vulnerability Scoring System (CVSS) Score Details
Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authorities (CNA) source for its products and services (see Red Hat classifications ).
| CVSS v3 Score Breakdown | Red Hat | NVD |
|---|---|---|
| CVSS v3 Base Score | 6.5 | |
| Attack Vector | Adjacent Network | |
| Attack Complexity | Low | |
| Privileges Required | None | |
| User Interaction | None | |
| Scope | Unchanged | |
| Confidentiality Impact | None | |
| Integrity Impact | None | |
| Availability Impact | High |

My product is listed as "Under investigation" or "Affected", when will Red Hat release a fix for this vulnerability?
- "Under investigation" doesn't necessarily mean that the product is affected by this vulnerability. It only means that our Analysis Team is still working on determining whether the product is affected and how it is affected.
- "Affected" means that our Analysis Team has determined that this product is affected by this vulnerability and might release a fix to address this in the near future.
What can I do if my product is listed as "Will not fix"?
Available options depend mostly on the Impact of the vulnerability and the current Life Cycle phase of your product. Overall, you have the following options:
- Upgrade to a supported product version that includes a fix for this vulnerability (recommended).
- Apply a mitigation (if one exists).
- Open a This content is not included.support case to request a prioritization of releasing a fix for this vulnerability.
What can I do if my product is listed as "Fix deferred"?
Available options depend mostly on the Impact of the vulnerability and the current Life Cycle phase of your product. Overall, you have the following options:
- Apply a mitigation (if one exists).
- Open a This content is not included.support case to request a prioritization of releasing a fix for this vulnerability.
- Red Hat Engineering focuses on addressing high-priority issues based on their complexity or limited lifecycle support. Therefore, lower-priority issues will not receive immediate fixes.
What is a mitigation?
I have a Red Hat product but it is not in the above list, is it affected?
Why is my security scanner reporting my product as vulnerable to this vulnerability even though my product version is fixed or not affected?
My product is listed as "Out of Support Scope". What does this mean?
