Description OSIDB Bzimport 2026-03-25 11:07:28 UTC 
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.
