Apple’s official website security content page says that a vulnerability in Safari web pages was fixed. The vulnerability name is WebKit. Processing maliciously crafted web content may lead to arbitrary code execution. This vulnerability has been actively exploited and is likely to be shared publicly.
macOS 12.2.1 Update
Apart from this, Apple began pushing the macOS 12.2.1 update (build number: 21D62) to Mac computer users.
The macOS Monterey 12.2.1 update is available for download on all eligible Macs through the Software Update section of System Preferences.
According to Apple’s release notes, macOS Monterey 12.2.1 resolves a bug that caused Bluetooth devices connected to the Mac to drain too much battery power.
After the macOS Monterey 12.2 update was out at the end of January this year, many users complained that they experienced excessive battery drain in sleep mode. Later, we learned that the Bluetooth accessories that frequently woke up their connected Macs were the reason.
Some affected users saw their Mac’s battery life drop from 100% to 0% in sleep mode after installing the macOS 12.2 update. Interestingly, both Intel-based Macs and Apple’s Silicon-based Macs were behaving in the same way. The problem stops when users disable Bluetooth or disconnect the Bluetooth accessory from the Mac. But this is not an ideal solution for users.
Apple addressed this issue in macOS Monterey 12.3 Beta 2. But now, Mac users won’t need to wait for macOS Monterey 12.3 to fix their Bluetooth-related battery drain issues.
macOS Monterey 12.2.1 also fixes a WebKit vulnerability. The latter could allow maliciously crafted web content to lead to arbitrary code execution. Apple said it was aware of reports. So Mac users should update to the new software as soon as possible.
Finally, Apple also released a new version of Safari 15.3 for users on macOS Big Sur and Catalina. We guess it addresses the same WebKit vulnerability fixed in macOS Monterey 12.2.1.
Last year, Apple told us that we can still stay on iOS 14 and receive security updates. In other words, we don’t have to upgrade to iOS 15. But this didn’t last long. We mean the company is no longer updating iOS 14. So you have to be on iOS 15 to remain secure.
