Kinda bummed tbh - I had 38 reports marked for a Fall 2026 fix, but only 7 ended up shipping in this release.
Guess the rest are cooking for later lol.
Sharing details & PoC for CVE-2026-43748, a heap OOB-write in ANEHWDevice::ANE_ProgramCheckandPrewireBuffers_gated (Apple Neural Engine)
Vulnerability was fixed in iOS 26.6 update. And for some reason, Apple missed me in advisory...
Frustrating :(
