Two weeks after the release of iOS 15.4, macOS 12.3 Monterey, and company, Apple has released minor updates for all of its current operating systems to fix bugs and eliminate security vulnerabilities (see “Apple Releases iOS 15.4, iPadOS 15.4, macOS 12.3 Monterey, watchOS 8.5, tvOS 15.4, and HomePod Software 15.4,” 14 March 2022).
iOS 15.4.1 and iPadOS 15.4.1
iOS 15.4.1 (266.6 MB on an iPhone 11 Pro) and iPadOS 15.4.1 (181.5 MB on an eighth-generation iPad) fix bugs introduced in iOS 15.4 and iPadOS 15.4, the most notable being a nasty battery drain that I and other TidBITS readers have been experiencing. The updates also fix accessibility bugs with unresponsive Braille readers and hearing devices losing connection with some third-party apps.
Equally as important, these updates fix one actively exploited security issue that allowed attackers to execute code with kernel privileges. If you’re running iOS 15.4 or iPadOS 15.4, you should install these updates right away.
macOS 12.3.1 Monterey
The macOS 12.3.1 (1.34 GB) update also fixes some hardware-specific bugs introduced in macOS 12.3, including problems with installing 12.3 on recent MacBook Pro models, display problems with some 2018 Mac mini models, and Beats headphone-related Bluetooth disconnects.
macOS 12.3.1 addresses two security flaws: the aforementioned arbitrary code bug and an exploit in the Intel graphics driver that could let an attacker read data from memory. Both have been actively exploited in the wild, so everyone running Monterey should update now.
watchOS 8.5.1, tvOS 15.4.1, and HomePod Software 15.4.1
Apple’s second-string operating systems also received updates, but details are light. It’s hard to feel much urgency in installing these updates, but it’s undoubtedly worthwhile at some point soon.
- The watchOS 8.5.1 release notes mention “security updates and bug fixes,” but it has no published CVE entries (544 MB for an Apple Watch Series 4).
- tvOS 15.4.1 “includes stability improvements when setting up or restoring your Apple TV.” Again, it has no published CVE entries.
- Did you notice some HomeKit devices not responding properly through a HomePod after installing HomePod Software 15.4? HomePod Software 15.4.1 fixes that. (467.7 MB)
