CVE-2026-104045: Sssd: sssd: denial of service via race condition in autofs responder

Noroxi assessment

Priority: Monitor (action score 18/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.12% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: sssd (SUSE:Linux Enterprise Server 15 SP6-LTSS) 2.10.2-150600.3.58.1.

Low priority for now. Upgrade to sssd (SUSE:Linux Enterprise Server 15 SP6-LTSS) 2.10.2-150600.3.58.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A flaw was found in SSSD. A local user can trigger a Denial of Service (DoS) by exploiting a race condition in the autofs responder between asynchronous enumeration completion and map invalidation. By repeatedly sending concurrent map enumeration and invalidation requests, an attacker can cause memory to leak, leading to excessive memory consumption that can disrupt or crash the autofs service.
