CVE-2023-53542

Kernel panic via incorrect MIPI PHY binding

Published Oct 4, 2025 · Updated Oct 4, 2025

Kernel panic in Linux 4.2 through 6.2.2 allows local users to crash Exynos5420 systems by exercising the MIPI video PHY. The exynos5420.dtsi device tree labels the MIPI video PHY with the generic samsung,s5pv210-mipi-video-phy compatible, so the kernel selects a driver path that lacks Exynos5420 handling. Exploitation requires local low-privileged access to an Exynos5420 system and interrupts the host by panicking its kernel.
