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 is available that zero-initializes the typec_partner_desc structure in the tps6598x_connect() function. Users should update their Linux kernel to a version that includes this patch. Since this is a kernel vulnerability, applying the official kernel update is the recommended remediation.

Description

A vulnerability in the Linux kernel's USB Type-C driver (tipd) was resolved by zero-initializing the typec_partner_desc structure in the tps6598x_connect() function. The flaw involved uninitialized fields in a stack-allocated descriptor, which could lead to garbage function pointers being stored and potentially invoked, as well as leaking stack data via sysfs. This issue was fixed by ensuring all fields are properly zero-initialized before use.
