    Not sure what you’re meaning? A CVE like this: https://nvd.nist.gov/vuln/detail/CVE-2025-24201 found in 2025 impacts iOS versions before 18.3.1 (Safari and iOS are shipped together). Which means there is a decent chance an iPad running 9.3.2 is vulnerable.

    Patch-day rule: Apple ships fixes in the advisory that discloses a bug, and this advisory states that fixed versions exist. So the vendor statement, first fix and fix for all versions all take the advisory's publication time.
