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
A Speculative Race Condition (SRC) vulnerability that impacts modern CPU architectures supporting speculative execution (related to Spectre V1) has been disclosed. An unauthenticated attacker can exploit this vulnerability to disclose arbitrary data from the CPU using race conditions to access the speculative executable code paths.

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

A Speculative Race Condition (SRC) vulnerability affecting modern CPUs with speculative execution, related to Spectre V1. An unauthenticated attacker can exploit race conditions during speculative execution to access and disclose arbitrary data from CPU memory through speculative code paths.

MitigationApply CPU microcode updates from hardware vendors and keep operating systems patched. Consider enabling kernel mitigation parameters (e.g., 'spec_store_bypass_disable' or 'mitigations=auto') and deploying software-level protections such as compiler-based mitigations for speculative store bypass.

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. Identify your CPU model and vendor
    On Linux, run `lscpu | grep -E '^(Model name|Vendor ID)'` or read /proc/cpuinfo. On Windows, run `wmic cpu get Name,Manufacturer` or check System Information.
    Affected if The CPU is a modern processor with speculative execution capability (most x86/ARM CPUs from the past decade)
  2. Check if the system reports Spectre V1 vulnerability status
    On Linux, examine the kernel vulnerability file: `cat /sys/devices/system/cpu/vulnerabilities/spectre_v1` if it exists. This file exposes the mitigation state.
    Affected if The output shows 'Vulnerable' or an unmitigated status rather than 'Mitigation' or 'Not affected'
  3. Verify CPU microcode version is up to date
    On Linux, check microcode version with `dmesg | grep -i microcode` or `cat /sys/devices/system/cpu/microcode/version`. Compare against the latest microcode available from your CPU vendor.
    Affected if The loaded microcode version is outdated or no microcode update has been applied
  4. Check kernel mitigation parameters at boot
    Inspect boot parameters via `cat /proc/cmdline` or `grubby --default-kernel` output. Look for mitigations settings such as 'mitigations=auto', 'spec_store_bypass_disable', or related flags.
    Affected if Boot parameters do not include kernel mitigations for speculative execution vulnerabilities, or are set to 'mitigations=off'
  5. Query system vulnerability status via system management interfaces
    On Linux, use vendor-specific tools if available (e.g., `amdgpu-sysinfo` for AMD, `intel-sysinfo` for Intel). On Windows, run `Get-CimInstance -ClassName Win32_Processor | Select-Object Name,Manufacturer` and cross-reference with vendor security advisories.
    Affected if The system reports the CPU as vulnerable to Spectre-class speculative execution flaws without active mitigations

Your environment is affected if you are running vulnerable CPU hardware with speculative execution enabled and without kernel or microcode mitigations 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.

From vendor data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply CPU microcode updates from hardware vendors and keep operating systems patched. Consider enabling kernel mitigation parameters (e.g., 'spec_store_bypass_disable' or 'mitigations=auto') and deploying software-level protections such as compiler-based mitigations for speculative store bypass.
