Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 18 Sep 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade Red Hat go-toolset:rhel8 to 8.3.

AI-suggested

Red Hat has released updated go-toolset packages for Red Hat Enterprise Linux 8.2 that address these vulnerabilities. Users should apply the security update RHSA-2025:23740 to remediate these issues. Detailed update instructions are available from Red Hat's official advisory and article https://access.redhat.com/articles/11258. No additional mitigation steps are indicated or required beyond applying the official update.

Description

Go Toolset provides the Go programming language tools and libraries. Go is alternatively known as golang. Security Fix(es): * os/exec: Unexpected paths returned from LookPath in os/exec (CVE-2025-47906) * golang: archive/tar: Unbounded allocation when parsing GNU sparse map (CVE-2025-58183) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Impact

The vulnerabilities could allow attackers to exploit unexpected path resolution behavior and unbounded memory allocation during archive parsing, potentially leading to security issues such as denial of service or other impacts related to resource exhaustion. However, the overall impact is considered moderate by Red Hat. There are no reports of active exploitation in the wild.

Summary

The Red Hat security advisory RHSA-2025:23740 reports two vulnerabilities in the Go Toolset for RHEL 8.2. CVE-2025-47906 is related to the os/exec package's LookPath function returning unexpected paths, which could lead to security issues in path resolution. CVE-2025-58183 involves the archive/tar package where parsing GNU sparse map files can cause unbounded memory allocation, potentially leading to resource exhaustion. These vulnerabilities affect the go-toolset packages in RHEL 8.2 and have been addressed in updated packages provided by Red Hat. The advisory does not provide CVSS scores but rates the impact as moderate. No known exploits in the wild have been reported.

CWE-440Expected Behavior Violation (opens in a new tab)
Base weakness
A feature, API, or function does not perform according to its specification.
CWE-770Allocation of Resources Without Limits or Throttling (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #25
The product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated.
Requirements
Clearly specify the minimum and maximum expectations for capabilities, and dictate which behaviors are acceptable when resource allocation reaches limits.
Architecture and Design
Limit the amount of resources that are accessible to unprivileged users. Set per-user limits for resources. Allow the system administrator to define these limits. Be careful to avoid CWE-410.
Architecture and Design
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended.
