Question about iOS Security Patch Levels

Hi all,

I am not an Intune admin, but an agent that supports devices in Intune.  I'm looking at a report of our Intune's Security Patches w/ iOS (mobile) devices - most of the iOS phones in our environment show the patch level as (blank), but on occasion I'll see a patch level (a) or (c).  I'm assuming (a) is an earlier update level than (c), but interestingly it's not clear to me from the https://support.apple.com/en-us/HT201222 or the https://en.wikipedia.org/wiki/IOS_version_history what a or c mean.  I'm assuming that having a blank security patch level is bad, but can someone point me to a resource to help me understand what I'm looking at?  Meaning if a user's mobile's iOS version is 13.6 and its security patch level is (blank) does that mean that it isn't patched at all, that the device is obsolete so it's "unpatched" since it's not running a modern OS, or that it just doesn't have a version a or c patch for that particular OS?  

 

Thanks for answering my newbie questions 🙂

    Rapid Security Responses (RSRs) are a new type of software release for iPhone, iPad, and Mac. They deliver important security improvements between software updates—for example, improvements to the Safari web browser, the WebKit framework stack, or other critical system libraries.

    RSRs are identified by a letter after the software version number. For example, iOS 16.5.1 (a) and iPadOS 16.5.1 (a) are the first RSRs for iOS 16.5.1 and iPadOS 16.5.1, respectively.


    iOS security patch levels (a) and (c) refer to the first and third RSRs for a given OS version, respectively.


    If a user's mobile's iOS version is 13.6 and its security patch level is (blank), it means that the device has not been patched at all.
    This could be because the device is obsolete, or because it has not been updated to the latest OS version, or because it has not been updated to the latest RSR for iOS 13.6.

    It is important to keep devices patched to the latest security patch level to protect them from known security vulnerabilities.
