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 and included in updated Linux kernel versions. Users should upgrade to patched kernel versions to resolve this issue. Refer to the Ubuntu Security Notice USN-8094-1 for specific patched versions and update guidance.

Description

A vulnerability in the Linux kernel's Intel Stratix 10 firmware driver (stratix10-svc) was fixed. The issue involved incorrect usage of platform_set_drvdata and dev_set_drvdata functions, which overwrite each other's data. This bug caused the removal of the svc driver (rmmod) to fail and triggered a kernel panic during kthread_stop and fifo free operations. The flaw has been addressed in updated Linux kernel versions.

Impact

The vulnerability could cause kernel panics when attempting to remove the svc driver, leading to denial of service conditions on affected systems. There is no indication of remote exploitation or privilege escalation from this issue. No known exploits are reported in the wild.

Summary

The Linux kernel contained a bug in the Intel Stratix 10 firmware driver (stratix10-svc) related to improper handling of driver data pointers via platform_set_drvdata and dev_set_drvdata. Both functions were used incorrectly on the same data, causing them to override each other. This led to failure in unloading the svc driver and resulted in kernel panics during thread stopping and FIFO freeing. The issue has been resolved in patched kernel releases.
