Exploitation evidence

Disclosed: evidence found.
CVE published 24 Sep 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 2026-10-26.

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.

AI-suggested

Red Hat has released updated kernel packages that address these vulnerabilities. Users of Red Hat Enterprise Linux 7 Extended Life Cycle Support should apply the provided kernel update as described in the Red Hat article https://access.redhat.com/articles/11258. A system reboot is required for the update to take effect. There is no indication that additional mitigations are necessary beyond applying the official update.

Description

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * hw: cpu: intel: Native Branch History Injection (BHI) (CVE-2024-2201) * kernel: wifi: mac80211: Avoid address calculations via out of bounds array indexing (CVE-2024-41071) 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 impact the core Linux kernel on affected Red Hat Enterprise Linux 7 Extended Life Cycle Support systems. CVE-2024-2201 involves a CPU-level branch history injection issue that could potentially affect CPU behavior. CVE-2024-41071 involves out-of-bounds memory access in the WiFi subsystem, which could lead to memory corruption or crashes. The advisory classifies the security impact as Important (high severity). No known exploits in the wild have been reported at the time of the advisory.

Summary

This advisory covers security fixes in the Linux kernel packages for Red Hat Enterprise Linux 7 Extended Life Cycle Support. The first vulnerability, CVE-2024-2201, concerns Intel CPU Native Branch History Injection (BHI), categorized under CWE-1423. The second, CVE-2024-41071, addresses an out-of-bounds array indexing issue in the mac80211 WiFi kernel component, categorized under CWE-787. The update mitigates these issues by patching the kernel packages. The advisory references Red Hat Bugzilla entries 2268118 and 2300448 for the respective CVEs. The update requires a system reboot to take effect.

CWE-1423Exposure of Sensitive Information caused by Shared Microarchitectural Predictor State that Influences Transient Execution (opens in a new tab)
Base weakness
Shared microarchitectural predictor state may allow code to influence transient execution across a hardware boundary, potentially exposing data that is accessible beyond the boundary over a covert channel.
Architecture and Design
The hardware designer can attempt to prevent transient execution from causing observable discrepancies in specific covert channels.
Architecture and Design
Hardware designers may choose to use microarchitectural bits to tag predictor entries. For example, each predictor entry may be tagged with a kernel-mode bit which, when set, indicates that the predictor entry was created in kernel mode.
Architecture and Design
Hardware designers may choose to sanitize microarchitectural predictor state (for example, branch prediction history) when the processor transitions to a different context, for example, whenever a system call is invoked.
From MITRE CWE, MITRE CAPEC and OWASP (Top 10, OpenCRE).
CWE-787Out-of-bounds Write (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #5
The product writes data past the end, or before the beginning, of the intended buffer.
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 · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Operation · Build and Compilation · Environment Hardening
Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index…
