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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat OpenShift Container Platform 4 · no fix planned: Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, … · updated 2026-10-06 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-80048.json)","depth":"twilight","depthScore":42,"depthScoreParts":{"impact":30.3,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[{"seq":217717,"id":"CVE-2026-80048","ts":1791406368995,"field":"exploit_available","old":"false","new":"true"},{"seq":217716,"id":"CVE-2026-80048","ts":1791406368995,"field":"cvss","old":null,"new":"5.5"},{"seq":217218,"id":"CVE-2026-80048","ts":1791360748022,"field":"severity","old":"none","new":"medium"}]}
