A local user or process able to connect to the `sssd-kcm` UNIX socket can exploit this vulnerability. By sending a large request length header and then stalling the connection, an attacker can cause the system to preallocate significant memory. This leads to memory exhaustion within the `sssd-kcm` responder, resulting in a Denial of Service (DoS) for affected deployments.","cvssScore":5.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-770"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-80048","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2479377","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2479377","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
