Apple’s latest operating systems for its most popular devices — iPhones, iPads and Macs — include patches for multiple vulnerabilities, but the company didn’t issue any warnings about active exploitation.
Apple patched 27 defects with the release of iOS 26 and iPadOS 26 and 77 vulnerabilities with the release of macOS 26, including some bugs that affected software across all three devices. Apple’s new operating systems, which are now numbered for the year of their release, were published Monday as the company prepares to ship new iPhones later this week.
Users that don’t want to upgrade to the latest versions, which adopt a translucent design style Apple dubs “liquid glass,” can patch the most serious vulnerabilities by updating to iOS 18.7 and iPad 18.7 or macOS 15.7. Most Apple devices released in 2019 or earlier are not supported by the latest operating systems.
None of the vulnerabilities Apple disclosed this week appear to be under active attack, Dustin Childs, head of threat awareness at Trend Micro’s Zero Day Initiative, told CyberScoop.
Apple previously issued an emergency software update to customers last month to patch a zero-day vulnerability — CVE-2025-43300 — that was “exploited in an extremely sophisticated attack against specific targeted individuals,” the company said in a series of updates for iOS, iPadOS and macOS.
The company has addressed five actively exploited zero-days this year, including defects previously disclosed in January, February, March and April. Seven Apple vulnerabilities have been added to the Cybersecurity and Infrastructure Security Agency’s known exploited vulnerabilities catalog this year.
Unlike many vendors, Apple doesn’t provide details about the severity of vulnerabilities it addresses in software updates. Childs noted it would be helpful if Apple issued some sort of initial severity indicator alongside the vulnerabilities it patches — even if it doesn’t follow the Common Vulnerability Scoring System.
A pair of vulnerabilities patched in macOS — CVE-2025-43298, which affects PackageKit, and CVE-2025-43304, which affects StorageKit — are concerning because exploitation could allow an attacker to gain root privileges, Childs said.
“On the iOS side, I don’t see anything that makes me sweat immediately but there are a lot of bugs addressed,” he added.
Apple also patched seven defects in Safari 26, 19 vulnerabilities in watchOS 26, 18 bugs in visionOS 26 and five defects in Xcode 26.
More information about the vulnerabilities and latest software versions are available on Apple’s security releases site.
