Exploitation evidence

Disclosed: evidence found.
CVE published 16 Dec 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 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 460e0dc9af2d7790d5194c6743d79f9b77b58836, 77a196ca904d66c8372aa8fbfc1c4ae3a66dee2e, 3fc36ae6abd263a5cbf93b2f5539eccc1fc753f7 or 2eb6a5f6adb7d494962a1d1995c47dbbc13a8460.

Description

In the Linux kernel, the following vulnerability has been resolved: tty: serial: ip22zilog: Use platform device for probing After commit 84a9582fd203 ("serial: core: Start managing serial controllers to enable runtime PM") serial drivers need to provide a device in struct uart_port.dev otherwise an oops happens. To fix this issue for ip22zilog driver switch driver to a platform driver and setup the serial device in sgi-ip22 code.
