CVE-2026-88252
A flaw was found in sssd. A local user can cause a Denial of Service DoS by exhausting the responder service's available file descriptors system handles used for open connections. By opening and maintaining many concurrent connections to a responder socket while continuing to queue new connection...
CVE-2026-88252
A Denial of Service (DoS) vulnerability exists in sssd where a local user can exhaust the responder service's available file descriptors . By maintaining numerous concurrent connections to a responder socket and queuing new attempts, an attacker triggers an unthrottled retry loop . This results i...

DEBIAN-CVE-2026-104040
A flaw was found in SSSD. When configured with the Entra ID identity provider, input lookup names containing single quotes are not properly escaped before being included in Microsoft Graph Open Data Protocol OData queries. A low-privileged local user can exploit this flaw by submitting a crafted...
DEBIAN-CVE-2026-104044
A flaw was found in sssd. A local attacker can trigger a Denial of Service DoS by sending a specially crafted Pluggable Authentication Module PAM request when passkey authentication is enabled. Due to a missing state validation check in passkey Kerberos handling, the PAM responder dereferences an...
DEBIAN-CVE-2026-104039
A flaw was found in SSSD. A local user can cause a denial of service DoS by disrupting system authentication services. When handling Generic Security Services Application Programming Interface GSSAPI authentication in the Pluggable Authentication Module PAM responder, cached connection state is...
DEBIAN-CVE-2026-104041
A flaw was found in SSSD. An unprivileged local user can repeatedly request lookups for nonexistent entries through the Name Service Switch NSS responder. Because the negative cache does not limit the total number of stored entries and only removes expired records when an existing key is rechecke...
DEBIAN-CVE-2026-104043
A flaw was found in SSSD. A local attacker with access to the Name Service Switch NSS responder UNIX socket can trigger an integer underflow by sending a specially crafted request with an undersized packet header. This issue causes an out-of-bounds memory read during packet parsing, crashing the...
DEBIAN-CVE-2026-104042
A flaw was found in sssd. A local attacker can cause a Denial of Service DoS by sending a crafted Pluggable Authentication Module PAM request containing a zero-length authentication token to the responder socket. Due to missing input validation, the service attempts to read beyond buffer boundari...
