Details

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

interconnect: qcom: sm8450: Fix NULL pointer dereference in icc_link_nodes()

The change to dynamic IDs for SM8450 platform interconnects left two links unconverted, fix it to avoid the NULL pointer dereference in runtime, when a pointer to a destination interconnect is not valid:
