It's a crash in the objdump standalone binary, it is a bug but AFAICT there's no security implication to this bug.

Comment 10 Siddhesh Poyarekar 2023-03-01 17:33:42 UTC

Also please note that none of these CVEs (CVE-2023-25584, CVE-2023-25585, CVE-2023-25587 or CVE-2023-25588) affect gdb in RHEL or Fedora.  gdb does not have or build the affected code.
