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

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debug-modules-core package and not the kernel-debug-modules-core 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:

bpf: Reject exclusive maps for bpf_map_elem iterators

Exclusive maps (aka excl_prog_hash) are meant to be reachable only from the single program whose hash matches. This is enforced by check_map_prog_compatibility() when the map is referenced from a program such as signed BPF loaders.

A bpf_map_elem iterator, however, binds its target map at attach time in bpf_iter_attach_map() instead of referencing it from the program, so the exclusivity check is never reached. On top of that, the iterator exposes the map value as a writable buffer.
