CVE-2026-40426

Integer Underflow Enables Denial of Service in Intel NPU Driver

Integer underflow (wrap or wraparound) for the Intel(R) NPU Driver software before version 1.33.0 within Ring 3: User Applications may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (low) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

CVE-2026-97401

Unprivileged Command Execution Exploit in Eclipse Kura via ZIP Extraction

In Kura versions <= 5.6.2, `CommandCloudApp.execute()` extracts a caller-supplied ZIP archive into a caller-supplied directory inside the Kura JVM process before dispatching the command to the executor service. On a packaged Kura installation the JVM runs as `kurad` with `CAP_DAC_OVERRIDE`, while the configurable "Unprivileged" executor drops to the `kura` user via `su`. A caller with permissions `rest.command` who is intentionally restricted to unprivileged command execution (`privileged.command.service.enable=false`, the default) can therefore set `workingDirectory` to `/` and use the ZIP body to write or overwrite arbitrary files on the device as `kurad`, completely bypassing the unprivileged sandbox the operator selected. The command service is disabled by default since Kura 4.0.0 [1]. The issue does not apply when the command service is disabled. [1] https://github.com/eclipse-kura/kura/blob/f9f969231892769a269876b23f19fa0e8173e3df/kura/distrib/RELEASE_NOTES.txt#L94

CVE-2026-97891

Unbounded HTTP Session Allocation Leads to Resource Exhaustion in Eclipse Kura Web Console

In Eclipse Kura version 5.0.0 to 5.6.2, the Web Console allocates a new HTTP session for every request to its built-in authentication endpoints (/admin/auth, /admin/login/password, /admin/login/cert) before checking the HTTP method, parsing the request, or validating any submitted credentials, and does not limit how many such sessions can be allocated. An unauthenticated client that sends requests to these endpoints without honoring the returned session cookie can cause the server to allocate an unbounded number of sessions, exhausting the JVM heap and crashing the Kura process.
