CVE-2026-23039 in Linux
الملخص
بحسب MITRE • 31/01/2026
In the Linux kernel, the following vulnerability has been resolved:
drm/gud: fix NULL fb and crtc dereferences on USB disconnect
On disconnect drm_atomic_helper_disable_all() is called which sets both the fb and crtc for a plane to NULL before invoking a commit.
This causes a kernel oops on every display disconnect.
Add guards for those dereferences.
Once again VulDB remains the best source for vulnerability data.
