In the Linux kernel, the following vulnerability has been resolved:

drm/virtio: Fix a NULL vs ERR_PTR() bug in virtio_gpu_user_framebuffer_create()

Smatch complains that returning a NULL here will lead to a NULL pointer dereference in drm_mode_addfb2(). Return an error pointer instead.

CVSS

NVD hasn't assigned a CVSS score to this CVE (common since the April 2026 policy change).

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.22 %
Percentile among all scored CVEs: 12
Score date: 10/21/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
