sssd

A vulnerability in sssd-kcm allows a local user or process with access to the sssd-kcm UNIX socket to cause a denial of service by sending a large request length header and stalling the connection, leading to memory exhaustion. This flaw affects multiple specific versions of sssd. The issue results in a medium severity denial of service without impacting confidentiality or integrity.

CVE-2026-80048 is a vulnerability in the sssd-kcm component where a local user or process able to connect to the sssd-kcm UNIX socket can exploit the flaw by sending a large request length header and then stalling the connection. This causes the system to preallocate significant memory, leading to memory exhaustion within the sssd-kcm responder and resulting in a denial of service condition. The vulnerability affects numerous explicitly listed sssd versions. The CVSS v3.1 score is 5.5 (medium severity), with attack vector local, low attack complexity, low privileges required, no user interaction, unchanged scope, and impact limited to availability.

A flaw was found in sssd-kcm. A local user or process able to connect to the sssd-kcm UNIX socket can exploit this vulnerability. (CVE-2026-80048)

CVE-2026-80048 is a medium severity vulnerability in the sssd-kcm component of Red Hat Enterprise Linux 10. A local user or process with access to the sssd-kcm UNIX socket can exploit this flaw by sending a large request length header and stalling the connection. This causes the system to preallocate excessive memory, leading to memory exhaustion and a denial of service condition.

The vulnerability in sssd-kcm allows a local attacker to cause memory exhaustion by sending a large request length header and then stalling the connection on the UNIX socket. This triggers preallocation of significant memory, resulting in denial of service due to resource exhaustion within the sssd-kcm responder. The flaw requires local access and does not impact confidentiality or integrity.
