Description

In the Linux kernel, the following vulnerability has been resolved: usb: typec: ucsi: Fix null pointer dereference in trace 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 which causes a NULL pointer dereference in trace. Rather than return NULL, call typec_port_register_altmode to register DisplayPort alternate mode as a non-controllable mode when CONFIG_TYPEC_DP_ALTMODE is not enabled.

Affected configurations

• linux linux kernel (< 5.4.284) • linux linux kernel (>= 5.5 < 5.10.226) • linux linux kernel (>= 5.11 < 5.15.167) • linux linux kernel (>= 5.16 < 6.1.109) • linux linux kernel (>= 6.2 < 6.6.50) • linux linux kernel (>= 6.7 < 6.10.9)
