🛡️ CVE-2023-43122 — exynos-1080-firmware

How this vulnerability can be exploited

This issue can be reached with physical access to the device, attack complexity is low, an attacker needs administrative privileges on the target. A user must be tricked into taking some action. The scope is changed, meaning a successful attack can affect components beyond the vulnerable one. Rated impact: confidentiality high, integrity none, availability none.
