CVE-2026-23366

The CVE-2026-23366 entry concerns the Linux kernel DRM client component. A vulnerability in drm_client_modeset_probe can lead to a NULL pointer dereference when ‘modes’ fails to be allocated with kcalloc; if an error path calls modes_destroy on this NULL pointer, a crash can occur. The issue is r...
