Tenable has extracted the preceding description block directly from the Fedora 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.

  - A flaw was found in sssd. When authenticating with a YubiKey, the SSSD PAM responder can crash due to a     use-after-free vulnerability, where a memory pointer is incorrectly handled. A local attacker could     exploit this flaw by manipulating smartcard or YubiKey contents, leading to a denial of service that     disrupts authentication. This vulnerability also presents a potential for privilege escalation, although     it is difficult to exploit. (CVE-2026-12610)

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

The AlmaLinux 9.2 host has packages installed that are affected by a vulnerability as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1787894517 advisory.

According to the versions of the sssd packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

    A flaw was found in sssd. When authenticating with a YubiKey, the SSSD PAM responder can crash due to a     use-after-free vulnerability, where a memory pointer is incorrectly handled. A local attacker could     exploit this flaw by manipulating smartcard or YubiKey contents, leading to a denial of service that     disrupts authentication. This vulnerability also presents a potential for privilege escalation, although     it is difficult to exploit.(CVE-2026-12610)

    A path traversal flaw was found in SSSD's AD GPO provider. The ad_gpo_extract_smb_components() function     does not sanitize .. sequences in the gPCFileSysPath LDAP attribute, allowing an attacker with AD GPO     management access to write files outside the GPO cache directory as root. On default RHEL configurations     with SELinux enforcing, this can be used to inject Kerberos configuration leading to authentication     bypass.(CVE-2026-14476)

    A flaw was found in SSSD. The sss_nss_protocol_fill_initgr() function in the NSS responder pre-allocates     reply space for all group entries but does not shrink the packet when groups are skipped, causing     uninitialized heap bytes to be transmitted to the client. A local attacker can exploit this to disclose     cached directory data and heap layout information from the sssd_nss process.(CVE-2026-68744)

    A flaw was found in SSSD's LDAP sudo provider. When the ldap_sudo_search_base option is not explicitly     configured, SSSD searches the entire LDAP directory tree for sudoRole objects. An authenticated attacker     with write access to any subtree can inject a sudoRole object granting root-level sudo privileges on all     SSSD-enrolled hosts.(CVE-2026-14474)

    A flaw was found in SSSD. The extract_authtok_v1() function in the PAM responder does not validate the     auth_token_length field against the remaining buffer size before processing. A local attacker can exploit     this via a crafted protocol v1 request to the PAM responder socket, causing an out-of-bounds read and     process crash, resulting in a denial of service.(CVE-2026-68743)

    A flaw was found in sssd. When authenticating with a YubiKey, the SSSD PAM responder can crash due to a     use-after-free vulnerability, where a memory pointer is incorrectly handled. A local attacker could     exploit this flaw by manipulating smartcard or YubiKey contents, leading to a denial of service that     disrupts authentication.
