AlienVault OTX Malware

sssd

A vulnerability in sssd allows a remote attacker to cause a denial of service (DoS) by submitting a certificate missing an expected Security Identifier (SID) extension. When sssd is configured with SID-based certificate mapping rules, it does not verify the presence of the SID extension before processing, leading to a crash during authentication or lookup operations. This flaw affects multiple specific versions of sssd. The CVSS score is 5.9, indicating a medium severity impact focused on availability.

CVE-2026-104038 is a denial of service vulnerability in sssd caused by improper handling of certificates lacking the expected Security Identifier (SID) extension. In deployments where SID-based certificate mapping is configured, sssd fails to check for the presence of the SID extension before processing the certificate. This leads to a crash of the sssd process during authentication or lookup, resulting in a denial of service. The vulnerability affects numerous specific versions of sssd as listed, with no known exploits in the wild. The CVSS 3.1 base score is 5.9, reflecting network attack vector, high attack complexity, no privileges required, no user interaction, unchanged scope, and impact on availability only.
