Hi, The following vulnerability was published for sssd. CVE-2026-90994[0]: | A flaw was found in sssd, specifically within the PAM (Pluggable | Authentication Modules) responder's protocol v1 parser, | pam_parse_in_data(). A local client with access to the PAM | responder's UNIX socket can exploit this by negotiating protocol v1 | and sending an empty or truncated PAM request body. This can trigger | an out-of-bounds read, potentially causing the PAM responder to | terminate or restart, leading to a local denial of service. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
