VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A null pointer dereference issue has been resolved in the Linux kernel. The issue occurs when ucsi register altmode checks IS ERR for the alt pointer and treats NULL as valid. When CONFIG TYPEC DP ALTMODE is not enabled, ucsi register displayport returns NULL, causing a null pointer dereference in trace. To fix this, typec port register altmode is called to register DisplayPort alternate mode as a non-controllable mode when CONFIG TYPEC DP ALTMODE is not enabled.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
