CVE-2020-9909
An out-of-bounds read was addressed with improved bounds checking.
MEDIUM 5.9EPSS 1.80%
Does this matter?
Lower severity and a low EPSS score (1.80%). Track it; it rarely justifies an emergency change on its own.
Description
An out-of-bounds read was addressed with improved bounds checking. This issue is fixed in iOS 13.6 and iPadOS 13.6, tvOS 13.4.8, watchOS 6.2.8. An attacker that has already achieved kernel code execution may be able to bypass kernel memory mitigations.
