# CVE-2025-31200: Apple Multiple Products Memory Corruption Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run Apple Multiple Products. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2025-04-17, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2025-05-08 ; treat that as the outer limit, not the target.
- EPSS 20.9% , percentile 98: FIRST’s model estimates a 20.9% chance of exploitation activity in the next 30 days, higher than 98% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.

## What it is

A memory corruption issue was addressed with improved bounds checking. This issue is fixed in iOS 18.4.1 and iPadOS 18.4.1, macOS Sequoia 15.4.1, tvOS 18.4.1, visionOS 2.4.1, watchOS 11.5. Processing an audio stream in a maliciously crafted media file may result in code execution. Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on versions of iOS released before iOS 18.4.1.

## Affected products (CVE record)

- Apple iOS and iPadOS: < 18.4.1
- Apple macOS: < 15.4.1
- Apple tvOS: < 18.4.1
- Apple visionOS: < 2.4.1
- Apple watchOS: < 11.5

## Severity

- CISA-ADP CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`

## Exploitation

- CISA KEV: added 2025-04-17; federal due date 2025-05-08. Known ransomware use: Unknown.
- CISA required action: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
- CISA SSVC assessment: exploitation active , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 20.90% probability of exploitation activity in the next 30 days; percentile 98.
