Summary

A vulnerability in the SecureROM of some Apple devices can be exploited by an unauthenticated local attacker to execute arbitrary code upon booting those devices. This vulnerability allows arbitrary code to be executed on the device. Exploiting the vulnerability requires physical access to the device: the device must be plugged in to a computer upon booting, and it must be put into Device Firmware Update (DFU) mode. The exploit is not persistent; rebooting the device overrides any changes to the device's software that were made during an exploited session on the device. Additionally, unless an attacker has access to the device's unlock PIN or fingerprint, an attacker cannot gain access to information protected by Apple's Secure Enclave or Touch ID features.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
