Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

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.

Description

In the Linux kernel, the following vulnerability has been resolved: hwmon: (sht3x) Fix unaligned accesses Sashiko reports: In sht3x_update_client(), the 16-bit temperature and humidity values are extracted from a stack-allocated byte array using be16_to_cpup(). The pointers passed to this function are calculated as buf and buf + 3. Since the difference between the two pointers is an odd number of bytes, at least one of them is guaranteed to be at an unaligned offset. This will trigger an alignment fault on strict-alignment architectures such as ARMv5 or SPARC, resulting in a kernel panic. Fix the problem by using get_unaligned_be16() instead of be16_to_cpup(), and put_unaligned_be16() instead of cpu_to_be16().
