Exploitation evidence

Disclosed: evidence found.
CVE published 11 Dec 2024
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

An official security update from Red Hat is available for kernel-rt on Red Hat Enterprise Linux 9.2 Extended Update Support and Extended Life Cycle. Users should apply the update as described in Red Hat advisory RHSA-2024:10946 and reboot the system to activate the fix. No additional mitigation steps are indicated by the vendor.

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: bpf: Add BPF_PROG_TYPE_CGROUP_SKB attach type enforcement in BPF_LINK_CREATE (CVE-2024-38564) 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 vulnerability affects the BPF subsystem in the real-time Linux kernel, potentially allowing improper attach type usage in BPF_LINK_CREATE. Red Hat rates the security impact as low, indicating limited risk or exploitability. There are no known exploits in the wild at this time.

Summary

The vulnerability CVE-2024-38564 affects the kernel-rt packages of Red Hat Enterprise Linux 9.2, which provide the Real Time Linux Kernel. The security fix adds enforcement of the BPF_PROG_TYPE_CGROUP_SKB attach type during BPF_LINK_CREATE operations, addressing a weakness in the BPF subsystem. This fix is included in the kernel-rt update released by Red Hat Product Security under advisory RHSA-2024:10946. The update is rated as having a low security impact by Red Hat.

CWE-665Improper Initialization (opens in a new tab)
Class weaknessLikelihood of exploit: Medium
The product does not initialize or incorrectly initializes a resource, which might leave the resource in an unexpected state when it is accessed or used.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Requirements · Language Selection
Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Architecture and Design
Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Implementation
Explicitly initialize all your variables and other data stores, either during declaration or just before the first usage.
