How to fix?

There is no fixed version for Centos:10 kernel-rt-modules.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-modules package and not the kernel-rt-modules package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

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

regulator: tps6594: Fix device node reference leaks in multiphase loop

In tps6594_regulator_probe(), the multi-phase configuration loop calls of_find_node_by_name() to find buck nodes by name, and of_get_parent() twice to navigate to the PMIC parent node. None of the acquired node references (np, intermediate parent, np_pmic_parent) are ever released via of_node_put(), causing a reference leak on every loop iteration.

Additionally, of_find_node_by_name() can return NULL, but the result was immediately passed to of_node_full_name() and of_get_parent() without a NULL check, which could lead to a NULL pointer dereference.

Fix this by:

  • Adding a NULL check for np after of_find_node_by_name()
  • Storing the intermediate parent node in a local variable np_parent
  • Calling of_node_put() on np, np_parent and np_pmic_parent at the end of each loop iteration
