FRRouting/frr from v2.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the opaque_info_detail function at ospf_opaque.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted LS Update packet.

An update of the frr package has been released.

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0853 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2025-61107:
    FRRouting/frr from v4.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the     show_vty_ext_pref_pref_sid function at ospf_ext.c. This vulnerability allows attackers to cause a Denial     of Service (DoS) via a crafted LSA Update packet.

    CVE-2025-61106:
    FRRouting/frr from v4.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the     show_vty_ext_pref_pref_sid function at ospf_ext.c. This vulnerability allows attackers to cause a Denial     of Service (DoS) via a crafted OSPF packet.

    CVE-2025-61105:
    FRRouting/frr from v4.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the     show_vty_link_info function at ospf_ext.c. This vulnerability allows attackers to cause a Denial of     Service (DoS) via a crafted OSPF packet.

    CVE-2025-61104:
    FRRouting/frr from v4.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the     show_vty_unknown_tlv function at ospf_ext.c. This vulnerability allows attackers to cause a Denial of     Service (DoS) via a crafted OSPF packet.

    CVE-2025-61103:
    FRRouting/frr from v4.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the     show_vty_ext_link_lan_adj_sid function at ospf_ext.c. This vulnerability allows attackers to cause a     Denial of Service (DoS) via a crafted OSPF packet.

    CVE-2025-61102:
    FRRouting/frr from v4.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the     show_vty_ext_link_adj_sid function at ospf_ext.c. This vulnerability allows attackers to cause a Denial of     Service (DoS) via a crafted OSPF packet.

    CVE-2025-61101:
    FRRouting/frr from v4.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the     show_vty_ext_link_rmt_itf_addr function at ospf_ext.c. This vulnerability allows attackers to cause a     Denial of Service (DoS) via a crafted OSPF packet.

    CVE-2025-61100:
    FRRouting/frr from v2.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the     ospf_opaque_lsa_dump function at ospf_opaque.c. This vulnerability allows attackers to cause a Denial of     Service (DoS) under specific malformed LSA conditions.

    CVE-2025-61099:
    FRRouting/frr from v2.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the     opaque_info_detail function at ospf_opaque.c. This vulnerability allows attackers to cause a Denial of     Service (DoS) via a crafted LS Update packet.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - FRRouting/frr from v2.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the     opaque_info_detail function at ospf_opaque.c. This vulnerability allows attackers to cause a Denial of     Service (DoS) via a crafted LS Update packet. (CVE-2025-61099)

Note that Nessus relies on the presence of the package as reported by the vendor.
