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 · unedited
Insufficient Parameter Validation in the SchedGet() system call could allow an attacker with local access to cause a crash of the QNX Neutrino kernel.

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 · moderate confidence

The SchedGet() system call in QNX Neutrino RTOS lacks proper parameter validation. A local attacker can exploit this insufficiency by passing malformed parameters to the system call, triggering a kernel crash resulting in denial of service.

MitigationImplement robust parameter validation in the SchedGet() system call to ensure all input parameters are within acceptable bounds before processing. Restrict local access to privileged operations where possible.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm QNX Neutrino RTOS is in use
    Run 'uname -a' or check system documentation to verify the operating system is QNX Neutrino RTOS
    Affected if The system is not running QNX Neutrino RTOS (this CVE does not apply)
  2. Identify the QNX Neutrino RTOS version
    Run 'uname -v' or check '/usr/qnx640/boot' directory for version files; compare against any available QNX version information
    Affected if Unable to determine version or version falls within affected QNX Neutrino RTOS releases with unpatched SchedGet()
  3. Verify SchedGet() system call accessibility
    Check if unprivileged local users can invoke the SchedGet() syscall by examining process permissions and syscall access controls
    Affected if Unprivileged local users can call SchedGet() without restrictions
  4. Audit kernel parameter handling
    Review any kernel logs or crash dumps for prior incidents involving SchedGet() failures; check for existing parameter validation patches
    Affected if No parameter validation is implemented for SchedGet() and prior crashes have occurred with malformed parameters

A user is affected if the system runs an unpatched version of QNX Neutrino RTOS where local unprivileged access to the SchedGet() system call is permitted and no parameter validation hardening is in place.

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.
