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 is available in the Linux kernel. The issue has been resolved by ensuring that interrupts are only unmasked when the ACTIVE state is true, preventing the race condition. Users and administrators should update to a Linux kernel version that includes the fix (commits identified by hashes 5346b1cec6afa4f9b4b49a9f84e3cfef95a3f7bb, 77abc1837c9651c8f43f7f7f336d10093eeb7745, 60f58da15f8c8e39706c564f9251de3626636dce, 49d349c42cf5ebaa878d02699c632c9d883d935f, or 0b4a0fb98b9ffeac36798bbd369c821605cae70f). No additional mitigation steps are required beyond applying the official fix.

Description

CVE-2026-99005 is a race condition vulnerability in the Linux kernel's drm/i915 graphics driver related to power management interrupt handling. The flaw allows unmasking of interrupts when the graphics technology (GT) is parked and the runtime power management wakelock is dropped, potentially causing kernel tainting due to hardware access without proper wakelock. This issue arises from a timing window between checking an ACTIVE state and queuing work that can execute after the GT is parked. The vulnerability has been fixed by ensuring interrupts are only unmasked when the ACTIVE state is true.

Impact

If exploited, this race condition can cause the kernel to perform hardware register writes without holding the necessary runtime power management wakelock, leading to kernel tainting and potential instability. While this does not directly indicate a security breach or privilege escalation, it can affect system stability and reliability by violating power management assumptions in the kernel graphics driver.
