CVE-2026-44064
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn out-of-bounds read in ASP session ID handling in Netatalk 1.3 through 4.4.2 allows an adjacent network attacker to obtain limited information or cause a denial of service via a crafted ASP request.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAn out-of-bounds read vulnerability exists in Netatalk's ASP (AppleTalk Session Protocol) session ID handling across versions 1.3 through 4.4.2. An adjacent network attacker can send a crafted ASP request containing a malicious session ID value that reads beyond allocated buffer boundaries, potentially exposing limited memory contents or triggering a denial of service condition.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Detect Netatalk installationSearch for the Netatalk daemon or binary on the system. Common locations include /usr/sbin/netatalk, /usr/local/sbin/netatalk, or check for the 'netatalk' package via system package manager (dpkg -l netatalk, rpm -qa netatalk, or similar).Affected if Netatalk is installed on the system
-
Determine installed Netatalk versionRun 'netatalk -V' or 'netatalk --version' to obtain the installed version number. If not available via command, check package metadata or the binary file version.Affected if The version returned is between 1.3 and 4.4.2 (inclusive)
-
Verify ASP service is enabledCheck Netatalk configuration files (typically /etc/netatalk/netatalk.conf, afpd.conf, or aspd.conf) for ASP (AppleTalk Session Protocol) daemon configuration. Look for 'aspd' or 'ASP' entries indicating the ASP service is actively configured.Affected if The ASP service daemon (aspd) is enabled or configured in Netatalk.conf
-
Assess ASP network exposureReview firewall rules, network binding configuration, or Netatalk's 'athost' settings to determine if the ASP service is reachable from adjacent network segments. Check if the service listens on accessible network interfaces.Affected if The ASP service is bound to network interfaces accessible to adjacent attackers (not restricted to localhost or filtered by firewall)
The environment is affected if Netatalk versions 1.3 through 4.4.2 are installed AND the ASP (AppleTalk Session Protocol) service is enabled and accessible to adjacent network attackers.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate Netatalk to the latest patched version beyond 4.4.2, which should include proper bounds validation on session ID values in ASP request handling. If patching is not immediately feasible, restrict network access to the AFP/ASP service to trusted adjacent network segments.
