Description SMASH SMASH 2024-02-06 10:20:11 UTC 
A race condition was found in the Linux kernel's drm/exynos device driver in exynos_drm_crtc_atomic_disable() function. This can result in a null pointer dereference issue, possibly leading to a kernel panic or denial of service issue.

Comment 2 Marcus Meissner 2024-02-08 17:05:14 UTC 
SP4, SP5, SP6: 
config/arm64/default:# CONFIG_DRM_EXYNOS is not set
(armv7l has it, but we do not ship arm32bit product.)

I would declare us as unaffected.

Ok, thanks Markus, closing it as resolved.
