Exploitation evidence

Disclosed: evidence found.
CVE published 30 Jul 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 an official security update for the kernel-rt packages in Red Hat Enterprise Linux 9.2. Users should apply the update as detailed in the Red Hat advisory (https://access.redhat.com/articles/11258) and reboot the system for the changes to take effect. No additional mitigation steps are indicated beyond applying the official patch and rebooting.

Description

Red Hat has released a security advisory for the kernel-rt packages, which provide the Real Time Linux Kernel for systems requiring high determinism. The update addresses multiple vulnerabilities including a double free error in the uvcvideo driver (CVE-2024-57980), and several other issues affecting IPv6 multicast, WiFi firmware string printing, ext4 journaling, huge memory management, network scheduling, and TIPC encryption. The advisory rates the update as important and requires a system reboot after applying the patch.

Impact

The vulnerabilities addressed include memory corruption issues such as double free and use-after-free, which could lead to system instability or potential escalation of privileges if exploited. Other fixes address kernel networking and filesystem components that could cause errors or crashes. The advisory does not report known exploits in the wild. The overall impact is rated as important, indicating significant security concerns that warrant prompt patching.

Summary

This Red Hat security advisory covers multiple vulnerabilities in the kernel-rt packages for Red Hat Enterprise Linux 9.2, including CVE-2024-57980 (double free in uvcvideo error path), CVE-2025-21759 (IPv6 multicast RCU protection), CVE-2025-21905 (WiFi firmware string printing), CVE-2025-22113 (ext4 journaling update on error), CVE-2025-37958 (invalid pmd migration entry dereference), CVE-2025-38001 (reentrant enqueue in net_sched hfsc), and CVE-2025-38052 (use-after-free in net/tipc). The advisory provides fixes for these issues and requires rebooting the system to apply the update. The update is rated as important by Red Hat Product Security.

CWE-415Double Free (opens in a new tab)
Variant weaknessLikelihood of exploit: High
The product calls free() twice on the same memory address.
Architecture and Design
Choose a language that provides automatic memory management.
Implementation
Ensure that each allocation is freed only once. After freeing a chunk, set the pointer to NULL to ensure the pointer cannot be freed again. In complicated error conditions, be sure that clean-up routines respect the state of allocation properly.
Implementation
Use a static analysis tool to find double free instances.

CWE-416Use After Free (opens in a new tab)
Variant weaknessLikelihood of exploit: HighCWE Top 25 (2025): #7
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
Architecture and Design · Language Selection
Choose a language that provides automatic memory management.
Implementation · Attack Surface Reduction
When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.

Base weaknessCWE Top 25 (2025): #8
The product reads data past the end, or before the beginning, of the intended buffer.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design · Language Selection
Use a language that provides appropriate memory abstractions.

The product receives input from an upstream component, but it does not restrict or incorrectly restricts the input before it is used as an identifier for a resource that may be outside the intended sphere of control.
