How to fix?

There is no fixed version for Centos:10 kernel-64k-devel.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64k-devel package and not the kernel-64k-devel 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: of: fill in supply names in of_regulator_bulk_get_all()

of_regulator_bulk_get_all() returns an array it allocated itself, and fills in only the consumer of each entry. Every other way of getting a bulk array has the supply name set, because the caller provides it, and the core expects it to be there: regulator_bulk_enable() prints it when a supply fails to enable, so a caller that hands such an array to it dereferences uninitialised memory on that path.

Copy each name into the array's own allocation, right behind the entries, so that it shares the array's lifetime and callers still have nothing extra to free. That also retires the fixed 64 byte stack buffer the names were assembled in, which is_supply_name() never bounded the copy against.
