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 reduces the USB3 root hub post-resume hold time to 120ms, mitigating the issue. Disabling USB runtime power management is an alternative workaround but less optimal. Users and vendors should apply the updated Linux kernel version containing this fix once available.

Description

A vulnerability in the Linux kernel USB hub driver related to USB3 root hubs has been resolved by reducing the post-resume hold time from 200ms to 120ms. The previous 200ms hold time could trigger an issue on AMD platforms, causing crashes when Android adb repeatedly polls and wakes the USB subsystem. The fix optimizes the hold time for USB3 root hubs without affecting external hubs, improving stability and preventing crashes.
