CVE-2026-23366 - Vulnerability Details - OpenCVE

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

drm/client: Do not destroy NULL modes

'modes' in drm_client_modeset_probe may fail to kcalloc. If this
occurs, we jump to 'out', calling modes_destroy on it, which
dereferences it. This may result in a NULL pointer dereference in the
error case. Prevent that.

No CVSS v4.0

No CVSS v3.1

No CVSS v3.0

No CVSS v2

This CVE is not in the KEV list.

The EPSS score is 0.00017.
