Exploitation evidence

Disclosed: evidence found.
CVE published 18 Oct 2026
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

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 26 Oct 2026.

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 or the CVSS exploit maturity 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 Linux kernel to d54df2de22f9ac5b660d0ec898986f805e97c096, 62479b6e5df82cbdf3c4145130928f233fae78fb or 98dc9fababd1b7fb1a88b8362183baa5779c2394.

AI-suggested

A fix has been implemented in the Linux kernel to address this issue by canceling deferred work items in the thread exit process. Users should apply the official kernel updates that include this fix. Since this is a kernel-level fix, upgrading to a patched kernel version is the recommended remediation.

Description

A vulnerability in the Linux kernel's rust_binder component was resolved by ensuring deferred work items on a thread's todo list are properly canceled when the thread exits. Previously, these deferred work items were not cleaned up in the Thread::release() method if the thread died while having an active outgoing transaction.
