Exploitation evidence

Disclosed: evidence found.

Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: 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 6 Nov 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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 f6a7e00b81e35ef1325234925f2fe1e53b466f92, e4406cbdd915f702d2ed9ee8b30683a16b06c6ac, 14fceda28069fdbe1bb49cdb6e1774892b583348 or 7d517b255f669cedd09830214d55f2f413b34481.

AI-suggested

A fix is available and has been applied in specific Linux kernel commits. Users and administrators should update to a Linux kernel version that includes these fixes to prevent the kernel BUG caused by this vulnerability. No additional mitigation actions are required beyond applying the official patch.

Description

A vulnerability in the Linux kernel's ice driver related to PTP (Precision Time Protocol) call trace during PTP release has been fixed. The issue occurs if a PF reset happens when the PTP state is ICE_PTP_UNINIT, leading to an invalid state transition and a kernel BUG during driver unload. The fix prevents this invalid state transition by detecting the ICE_PTP_UNINIT state and returning without error in ice_ptp_rebuild().

Impact

This vulnerability can cause a kernel BUG and potential system instability or crash during driver unload if the PTP state is improperly transitioned. It specifically affects scenarios involving PF resets and PTP state management in the ice driver, such as when passing PF1 through to a VM. There is no indication of remote code execution or privilege escalation. No known exploits in the wild have been reported.
