Exploitation evidence

Disclosed: evidence found.
CVE published 16 Sep 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.

What to do

Upgrade Red Hat to 5.14.0-70.144.1.el9_0.

AI-suggested

Red Hat has released updated kpatch live patch modules to fix these vulnerabilities. Users should apply the provided updates for the affected kernel version and reboot the system to ensure the patches take effect. Refer to Red Hat's official update instructions at https://access.redhat.com/articles/11258. No additional mitigation steps are indicated by the vendor.

Description

Red Hat has issued a security advisory for kernel live patch modules targeting kernel-5.14.0-70.112.1.el9_0 in Red Hat Enterprise Linux 9.0. The update addresses two vulnerabilities: a slab-use-after-free read in the net/tipc component (CVE-2025-38052) and a race condition in posix-cpu-timers (CVE-2025-38352). These issues are fixed by updated kpatch modules that can be loaded to modify the running kernel code. A system reboot is required to apply the update effectively.

Impact

The vulnerabilities fixed by this update could allow an attacker to cause memory corruption or race conditions within the kernel, potentially leading to system instability or escalation of privileges. The advisory rates the security impact as Important (high severity). There are no known exploits in the wild at this time.

Summary

This advisory covers security fixes delivered via kpatch live patch modules for Red Hat Enterprise Linux 9.0 kernel version 5.14.0-70.112.1.el9_0. The first fix resolves a slab-use-after-free vulnerability in the tipc_aead_encrypt_done function of the net/tipc subsystem (CVE-2025-38052). The second fix addresses a race condition between handle_posix_cpu_timers() and posix_cpu_timer_del() functions (CVE-2025-38352). These vulnerabilities could lead to memory corruption and race condition issues in the kernel. The patches are distributed as kpatch modules and require a reboot for full effect.

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.

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.
