Today, Apple introduced the iOS 17.0.3 update, which includes a patch aimed at improving the iPhone overheating problem. The iPhone 15 Pro and iPhone 15 Pro Max faced a challenging launch due to multiple user complaints of overheating during both charging and specific app usage. This initial setback dampened enthusiasm for the new iPhones. However, Apple quickly acknowledged the heat-related concerns and committed to resolving them.
Apple releases iOS 17.0.3 Update
- The iOS 17.0.3 update is approximately 430MB in size (although this may vary depending on your iPhone model) and is currently being rolled to all eligible iPhones worldwide.
- Although there was speculation about possible hardware issues, such as concerns related to the stronger A17 Pro processor or the use of titanium components possibly causing heating problems, a recent statement from Apple has attributed the problem to a software issue.
- This is alongside when using USB-C chargers.
- Apple has released a new update following its previous patch that aims to resolve data transfer issues faced by a limited number of users.
- Apple is currently in the beta testing phase for the upcoming iOS 17.1 update, indicating that its release to the general public is imminent.
In an update outlining the security fixes within this patch, Apple identified two vulnerabilities, which were fixed for iOS and iPadOS. Among the two, the first was a kernel exploit that could be exploited by an attacker with local access to the device. Apple mentioned that it “may have been actively exploited against versions of iOS prior to iOS 16.6.”
The second fix is regarding a libvpx bug, which previously raised concerns flagged by CISA. This potentially allowed a remote takeover of the device. This libvpx bug was recently patched in applications like Chrome and Firefox.
Downgrading from iOS 17 to iOS 16 is no Longer Possible
While the fix to the heating issues aside, following the release of iOS 17.0.3, Apple has stopped signing iOS 16.1.1, iOS 17, and iOS 17.0.1, thereby preventing iPhone users from downgrading to any of the older software versions. However, Apple is continuing to sign iOS 17.0.2 for now.
This isn’t anything new as Apple usually stops signing older iOS releases over time to prevent users from downgrading to previous software versions.
