Technical summary
The supplied source corpus identifies the issue as an out-of-bounds write in Apple WebKit and shows that CISA placed it in the KEV catalog. The corpus does not include exploit details, a CVSS score, or Apple’s full fix notes, so the safest interpretation is limited to the confirmed vulnerability class, the Apple product scope, and the fact of known exploitation as reflected by KEV.
Defensive priority
Immediate. CISA KEV entries are treated as active remediation priorities, and this item has a due date of 2025-04-03 in the supplied timeline.
Recommended defensive actions
- Review Apple’s vendor advisories referenced in the KEV notes for the exact affected products and fixed versions.
- Apply Apple’s mitigations or updates as soon as they are available in your environment.
- Prioritize internet-facing and user-accessible Apple systems in your remediation plan.
- Track completion against the CISA KEV due date of 2025-04-03.
- If a mitigated or updated state cannot be achieved, follow CISA guidance to apply vendor mitigations or discontinue use of the product where required.
Evidence notes
Evidence is limited to the supplied CISA KEV record and official CVE/NVD links. The source item explicitly names the issue as an Apple Multiple Products WebKit out-of-bounds write vulnerability, marks it as a KEV entry, and provides the KEV dates (dateAdded 2025-03-13; dueDate 2025-04-03).
