Exploitation evidence

Disclosed: evidence found.
CVE published 8 Jan 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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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 2026-10-26.

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 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 redhat/kernel to 9.4.1.

AI-suggested

Red Hat has released an official security update for Red Hat Enterprise Linux 9.4 Extended Update Support that addresses these vulnerabilities. Users should apply the update promptly following Red Hat's guidance and reboot systems to activate the fixes. For detailed update instructions, refer to https://access.redhat.com/articles/11258. No additional mitigations are specified by the vendor.

Description

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: md: fix resync softlockup when bitmap size is less than array size (CVE-2024-38598) * kernel: i40e: fix race condition by adding filter's intermediate sync state (CVE-2024-53088) * kernel: mptcp: cope racing subflow creation in mptcp_rcv_space_adjust (CVE-2024-53122) 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 lead to kernel softlockups or race conditions that may affect system stability or reliability. While no known exploits are reported in the wild, these issues pose a risk of denial of service or unexpected behavior in affected kernel components.

Summary

The advisory covers three kernel vulnerabilities: CVE-2024-38598 fixes a softlockup during md resync caused by bitmap size being smaller than the array size; CVE-2024-53088 addresses a race condition in the i40e network driver by adding a filter's intermediate sync state; CVE-2024-53122 mitigates racing conditions in multipath TCP subflow creation. These issues affect Red Hat Enterprise Linux 9.4 Extended Update Support and related variants. The vendor has released an important security update that must be applied with a system reboot.

CWE-667Improper Locking (opens in a new tab)
Class weakness
The product does not properly acquire or release a lock on a resource, leading to unexpected resource state changes and behaviors.
Implementation · Libraries or Frameworks
Use industry standard APIs to implement locking mechanism.

CWE-362Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') (opens in a new tab)
Class weaknessLikelihood of exploit: MediumOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.
Architecture and Design
In languages that support it, use synchronization primitives. Only wrap these around critical code to minimize the impact on performance.
Architecture and Design
Use thread-safe capabilities such as the data access abstraction in Spring.
Architecture and Design
Minimize the usage of shared resources in order to remove as much complexity as possible from the control flow and to reduce the likelihood of unexpected conditions occurring.
