Exploitation evidence

Disclosed: evidence found.
CVE published 6 Nov 2026
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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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.

AI-suggested

A patch is available in Linux kernel version 6.8.0-1038.42 for NVIDIA Tegra systems. Users should update their systems to this version or later and reboot to apply all security fixes. Due to an ABI change, recompilation and reinstallation of any third-party kernel modules are required. No other specific mitigations are noted in the vendor advisory.

Description

Multiple security vulnerabilities were discovered in the Linux kernel for NVIDIA Tegra systems, including an issue in the io_uring subsystem that improperly handles canceled task work during certain wait operations. This flaw can cause operations to execute in the wrong task context, potentially allowing a local attacker to cause a denial of service (system crash). The update addresses numerous security flaws across a wide range of kernel subsystems and drivers. A patch is available and users are advised to update to the fixed kernel version and reboot. Due to ABI changes, third-party kernel modules may need recompilation.
