Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
A race condition was addressed with additional validation. This issue is fixed in iOS 17.6 and iPadOS 17.6, macOS Sonoma 14.6, macOS Ventura 13.6.8, tvOS 17.6, watchOS 10.6. A malicious attacker with arbitrary read and write capability may be able to bypass Pointer Authentication.
