CVE-2020-15293
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 · uneditedMemory corruption in IntLixCrashDumpDmesg, IntLixTaskFetchCmdLine, IntLixFileReadDentry and IntLixFileGetPath due to insufficient guest-data input validation may lead to denial of service conditions.
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 confidenceMemory corruption vulnerability in four hypervisor host-side functions (IntLixCrashDumpDmesg, IntLixTaskFetchCmdLine, IntLixFileReadDentry, IntLixFileGetPath) that handle data from guest virtual machines. Insufficient validation of guest-provided data allows malicious or malformed guest inputs to corrupt memory, leading to denial of service on the host.

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.
-
Verify Bitdefender Hypervisor Introspection is installedCheck for the presence of Bitdefender Hypervisor Introspection components on the system. This may be listed in installed software, system services, or kernel modules depending on deployment.Affected if The product is present on the system
-
Check the installed version of Bitdefender Hypervisor IntrospectionUse the appropriate method to query the installed version (e.g., software inventory, product-specific CLI tool, or system information). Compare the version number to the affected range.Affected if The installed version is exactly 1.132.2
-
Confirm hypervisor introspection feature is enabledVerify that the hypervisor introspection functionality is active and handling guest VM data. Check relevant configuration settings or service status that controls this feature.Affected if The hypervisor introspection feature is enabled and processing guest VM data
-
Check if the affected functions are activeInspect system logs, debugging interfaces, or product-specific diagnostics to determine if the vulnerable functions (IntLixCrashDumpDmesg, IntLixTaskFetchCmdLine, IntLixFileReadDentry, IntLixFileGetPath) are being invoked or loaded.Affected if Any of the four vulnerable functions (IntLixCrashDumpDmesg, IntLixTaskFetchCmdLine, IntLixFileReadDentry, IntLixFileGetPath) are active and handling guest data
A system is affected if Bitdefender Hypervisor Introspection version 1.132.2 is installed with the hypervisor introspection feature and its vulnerable functions enabled to process guest VM data.

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 dataImplement rigorous input validation on all data received from guest VMs before processing in these functions, including bounds checking and sanitization of guest-supplied pointers, sizes, and buffer lengths.
