How to fix?

There is no fixed version for Centos:9 kernel-64k-modules-partner.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64k-modules-partner package and not the kernel-64k-modules-partner package as distributed by Centos. See How to fix? for Centos:9 relevant fixed versions and status.

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

bpf: mark bpf_dummy_struct_ops.test_1 parameter as nullable

Test case dummy_st_ops/dummy_init_ret_value passes NULL as the first parameter of the test_1() function. Mark this parameter as nullable to make verifier aware of such possibility. Otherwise, NULL check in the test_1() code:

  SEC("struct_ops/test_1")
  int BPF_PROG(test_1, struct bpf_dummy_ops_state *state)
  {
        if (!state)
                return ...;

    ... access state ...

}

Might be removed by verifier, thus triggering NULL pointer dereference under certain conditions.
