In the Linux kernel, the following vulnerability has been resolved: bus: qcom: Put child node before return Put child node before return to fix potential reference count leak.
Does this matter?
Lower severity and a low EPSS score (0.24%). Track it; it rarely justifies an emergency change on its own.
Description
In the Linux kernel, the following vulnerability has been resolved: bus: qcom: Put child node before return Put child node before return to fix potential reference count leak. Generally, the reference count of child is incremented and decremented automatically in the macro for_each_available_child_of_node() and should be decremented manually if the loop is broken in loop body.
