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 2026-10-25.

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.

AI-suggested

Red Hat has released updated kernel-rt packages that address these vulnerabilities. Users should apply the security update as detailed in Red Hat's advisory (RHSA-2025:0066) and reboot affected systems to ensure the fixes take effect. Patch status is confirmed by the vendor advisory. No additional mitigation steps are indicated beyond applying the official update and rebooting.

Description

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix(es): * 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 involve race conditions in kernel components, which could lead to unpredictable behavior or potential denial of service in systems using the affected kernel-rt packages. The Real Time Linux Kernel is critical for systems requiring precise timing and determinism, so these issues could impact system stability or reliability if exploited. No known exploits in the wild have been reported at this time.

Summary

This advisory covers two race condition vulnerabilities in the Red Hat kernel-rt packages for Red Hat Enterprise Linux 8. CVE-2024-53088 addresses a race condition in the i40e network driver by adding a filter's intermediate synchronization state. CVE-2024-53122 addresses a race condition in multipath TCP (mptcp) subflow creation within the mptcp_rcv_space_adjust function. Both vulnerabilities could lead to potential synchronization issues in kernel operations. Red Hat has released updated kernel-rt packages to fix these issues, and a reboot is required to apply the updates.

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.
