CVE-2026-90391

A flaw was found in the Linux kernel. A local user could exploit a vulnerability in the dmirrorfault function. When a mirrored memory management mm structure has exited, dmirrorfault incorrectly returns a success code, causing the caller to enter an infinite retry loop. This can lead to a Denial ...

CVE-2026-88252 Sssd: sssd: denial of service via responder connection retry loop during file descriptor exhaustion

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...

hickory-resolver: Unbounded TC-retry loop in `NameServerPool::try_send` (resource-exhaustion DoS)

When the hickory-resolver name server pool implementation receives an upstream response with the TC truncated header bit set, it re-queues the request to the same nameserver to retry with UDP transport disabled. However, the retry arm never inspects the transport that just answered and carries no...
