No public nuclei template indexed

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 d71483f0716e7ae98578817bfdc8a5b822d250f8 or 5293e376e9d6cdb945db11f71821bb57d415631d.

AI-suggested

A fix has been implemented in the Linux kernel by moving the assignment of netdev_ops before the PHY attach in the Aeroflex ethernet driver. Users should update to the fixed kernel version once available. No other mitigation or workaround is indicated.

Description

A vulnerability in the Linux kernel's Aeroflex ethernet driver caused a crash due to a NULL pointer dereference during device probing when CONFIG_NET_SHAPER is enabled. The issue arises because the netdev_ops pointer was not assigned before PHY attachment, leading to a crash. This has been fixed by moving the assignment of netdev_ops before the PHY attach, similar to a previous fix in the emac driver.
