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

A fix has been implemented in the Linux kernel to validate string descriptor payload lengths properly and allocate sufficient buffer space, preventing out-of-bounds reads. Users should apply the official kernel updates that include this fix. Since this is a kernel-level vulnerability, updating to a patched kernel version is the recommended mitigation.

Description

A vulnerability in the Linux kernel's SCSI UFS core component involves improper validation of string descriptors. The issue arises because the UTF-16 payload length is misinterpreted as a byte count rather than a count of UTF-16 code units, leading to potential out-of-bounds reads. The vulnerability has been addressed by validating the payload length, correctly passing the code-unit count to the UTF-16 to UTF-8 converter, and ensuring proper buffer allocation to prevent overreads.
