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 30 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.
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 fix is available and has been applied in the Linux kernel. Users should update to a kernel version that includes the fix identified by the listed commit hashes. No additional mitigation is required beyond applying the official patch.

Description

A vulnerability in the Linux kernel's dmaengine dw-edma-pcie driver allows devices without driver data to be accepted, leading to a NULL pointer dereference. This occurs because the driver unconditionally copies the PCI device ID driver_data as a template for the controller layout. The issue is fixed by rejecting devices that lack this driver data before enabling them.

Impact

This vulnerability can cause a NULL pointer dereference in the kernel, which may lead to a kernel crash or denial of service. There is no indication of code execution or privilege escalation from the provided data.

Summary

The Linux kernel's dw-edma-pcie driver in dmaengine improperly handles PCI devices bound dynamically via sysfs that lack driver_data. The function dw_edma_pcie_probe() uses the driver_data as a template and copies it without checking if it is NULL, causing a NULL pointer dereference. The fix involves rejecting such devices without driver_data to prevent this condition.
