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 for this vulnerability has been implemented in the Linux kernel. Users should apply the official kernel updates that include this patch to resolve the issue. No additional mitigation steps are indicated.

Description

A vulnerability in the Linux kernel's XFS filesystem was resolved involving a resource leak when changing ownership (chown) of the orphanage directory inode fails. The issue caused the kernel to leak a grabbed reference to the orphanage directory inode, potentially leading to resource management problems.

Impact

The vulnerability results in a resource leak within the kernel's XFS filesystem code when chown fails on the orphanage directory inode. While this does not directly indicate privilege escalation or code execution, resource leaks can degrade system stability or lead to denial of service conditions over time.

Summary

The Linux kernel's XFS filesystem had a vulnerability where if the chown operation on the orphanage directory inode failed, the kernel leaked the igrab'd reference to that inode. This leak could cause resource mismanagement. The vulnerability has been fixed by ensuring the orphanage directory inode is properly released if chown fails.
