Apple's security notes for macOS Sequoia 15.8.2 list dozens of fixed flaws across system components such as APFS, AppleAVD, CoreAudio and CoreMedia. Several entries say a malicious app or a crafted file can gain root privileges, read or write kernel memory, or bypass Gatekeeper and privacy controls.
Summary written from the sources below. Check the originals before acting.
First seen by InfraStack 2026-10-29 04:33 UTC, 0h before NVD. All times on this page are UTC.
Any Mac running macOS Sequoia before 15.8.2 is affected, since the advisory covers system components that ordinary apps can reach. Attacks that need a malicious app or a crafted file are the main paths, so workstations that open untrusted files or run unvetted apps matter most. Machines already on 15.8.2 or a newer release can skip this entry.
