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

The vulnerability has been resolved in the Linux kernel by correcting the privilege check and properly filtering SMI events to restrict delivery to the owning process or CAP_SYS_ADMIN subscribers. Users should apply the official Linux kernel update that includes this fix. No additional mitigation steps are indicated.

Description

A vulnerability in the Linux kernel's drm/amdkfd component allows cross-process information leakage via SMI events. The flaw occurs because the function kfd_smi_ev_enabled() skips a superuser privilege check when the process ID (pid) is zero. This causes PROCESS_START, PROCESS_END, and VMFAULT events to be emitted with pid=0 but containing another process's PID and command name, enabling any user in the render group with access to /dev/kfd to monitor all GPU workloads.
