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.

AI-suggested

A fix has been implemented by assigning netdev_ops before the PHY attach call in the driver initialization code. Users should apply the updated Linux kernel version containing this fix. No additional mitigation steps are indicated.

Description

A vulnerability in the Linux kernel's ti icssm-prueth driver caused a crash due to a NULL pointer dereference when CONFIG_NET_SHAPER is enabled. The issue arises because netdev_ops was not assigned before a PHY attach call that reads it, leading to a crash during probing. This has been fixed by assigning netdev_ops prior to the PHY attach, aligning with a previous fix in a related driver.
