This is again a mere "vulnerability" being touted as an "exploit" without evidence such an exploit has been demonstrated in the wild, announced by Apple after the security updates have been pushed out to users of older iPhones for updating. The real risk here is that it also impact ALL users of older versionWebKit, a public domain kit of communications protocols developed and owned by Apple, which is used by almost all versions of Unix™, Linux, Android, their browsers and many Microsoft browsers as well as part of their standards. The vulnerability has been closed by Apple in Webkit’s latest releases but if your Android, Linux, Unix™, browser latest release is not updated, it may have one of the older version, and if your provider doesn’t provide upgrades, then you may have a problem with hackers taking advantage of that now known vulnerability and have to rely on anti-malware apps to detect any attempts to exploit it through websites or malicious emails. —PING!

As of April 6, 2021, over 90% of iPhone and iPad
users had already upgraded to iOS 14 or higher,
another ~5% were still on iOS 13, neither of which
are at risk from this vulnerability, and only 4.48%
were hardcore non-upgraders still operating iOS 12
or lower on their devices.

Apple has pushed out security updates to all users of iOS Safari 12, apparently where a major update to WebKit was introduced, along with the vulnerability, which was apparently fixed in a later revised version, as later versions of iOS are not vulnerable to this.

So the question remains, what version of WebKit is in various versions of Android, Linux, UNIX™, and those browsers? I’d suggest getting the latest updates to be certain you don’t have an old distribution from 2017-2018…
