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

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2026:3401-1 advisory.

    This update for sssd fixes the following issue:

    - CVE-2026-12610: cancelled or completed PAM request while the asynchronous child process is still running     can lead to a       use-after-free (bsc#1269807).

The remote SUSE Linux SLES12 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2026:3394-1 advisory.

    This update for sssd fixes the following issue:

    - CVE-2026-12610: cancelled or completed PAM request while the asynchronous child process is still running     can lead to a       use-after-free (bsc#1269807).

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1984 advisory.

    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 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 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 the System Security Services Daemon (SSSD). The pam_passkey_child_read_data() function     within the PAM passkey responder fails to properly handle raw bytes received from a pipe. Because the data     is treated as a NUL-terminated C string without explicit termination, it results in an out-of-bounds read     when processed by functions like snprintf(). A local attacker could potentially trigger this vulnerability     by initiating a crafted passkey authentication request, causing the SSSD PAM responder to crash, resulting     in a local Denial of Service (DoS). (CVE-2026-6245)
