iOS and iPadOS: Out-of-bounds Read

CVE-2026-64692 is a high-severity out-of-bounds read vulnerability in iOS and iPadOS from Apple, with a CVSS 3.1 base score of 7.1 out of 10. It can be exploited with local access to the system by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists versions 18.7.10, 26.6 as the first without the flaw, so updating iOS and iPadOS to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.16% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update iOS and iPadOS to 18.7.10 or 26.6, whichever matches your release line, or a later version.
  2. Update macOS to 14.8.8 or 15.7.8 or 26.6, whichever matches your release line, or a later version.
  3. Update tvOS to 26.6 or a later version.
  4. Read the advisory on support.apple.com for workarounds and exact fixed builds.
  5. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
