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

Apply the official fixes by updating to iOS 27.2, iPadOS 27.2, macOS Golden Gate 27.2, tvOS 27.2, visionOS 27.2, or watchOS 27.2. These updates include improved bounds checking that resolves the out-of-bounds write issue.

Description

An out-of-bounds write vulnerability in Apple operating systems was fixed by improved bounds checking. The flaw could be triggered by processing a maliciously crafted font, potentially causing unexpected app termination or memory corruption. The issue is resolved in iOS 27.2, iPadOS 27.2, macOS Golden Gate 27.2, tvOS 27.2, visionOS 27.2, and watchOS 27.2.

Impact

Successful exploitation of this vulnerability may lead to unexpected application termination or corruption of process memory, which could affect system stability or security depending on the context in which the malicious font is processed.

Summary

CVE-2026-113950 is an out-of-bounds write vulnerability affecting multiple Apple OS platforms. The vulnerability arises from insufficient bounds checking when processing font data, which could allow a crafted font to cause memory corruption or application crashes. Apple addressed this issue by improving bounds checking in the affected OS versions listed. There is no CVSS score provided, and no known exploits in the wild have been reported as of the publication date.
