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 has been applied to the Linux kernel to initialize the IRQ state before requesting the alarm IRQ. Users should update to the fixed kernel version once available. Since this is a kernel-level fix, applying the official kernel update is the recommended remediation.

Description

A vulnerability in the Linux kernel related to the RTC spear driver was resolved by initializing the IRQ state before requesting the alarm IRQ. The issue was that devm_request_irq() enables the interrupt before returning, potentially causing the interrupt handler to run while the device probe was still initializing. The fix involved initializing the MMIO address and spinlock prior to requesting the alarm IRQ.
