The vulnerability described is a denial of service (DoS) issue caused by infinite recursion leading to stack exhaustion and process crashes. It does not involve unauthorized access, data leakage, or modification of data.

Since the vulnerability results in service disruption but does not compromise confidentiality or integrity of data, its direct impact on compliance with standards like GDPR or HIPAA, which focus on data protection and privacy, is limited.

However, denial of service conditions can affect availability, which is a component of some security frameworks, so organizations relying on affected systems should consider the risk to service availability and implement mitigations accordingly.

The vulnerability arises from a flaw in the libefiboot device path node parser that fails to validate the Length field of each device path node. Detection involves identifying if the system processes specially crafted EFI device path nodes with a Length field less than 4 bytes, which triggers infinite recursion and a process crash.

However, the provided resources do not include specific detection commands or network/system scanning tools to identify exploitation attempts or vulnerable states.

To mitigate this vulnerability, the recommended immediate step is to apply the patch that adds a guard clause in the libefiboot device path node parser. This guard clause checks if the node length is less than 4 bytes and returns an error to prevent infinite recursion and process crashes.

• Update the efivar package to a version that includes the fix.
• Ensure that your system is running the patched libefiboot library where the parser validates the Length field properly.

Since the vulnerability requires local user access to provide a specially crafted device path node, restricting local user permissions and monitoring for unusual process crashes related to efivar may also help reduce risk.

The vulnerability in libefiboot causes a denial of service (DoS) through stack exhaustion and process crash but does not impact confidentiality or integrity of data.

Since the vulnerability does not lead to unauthorized data access or modification, it does not directly affect compliance with data protection standards such as GDPR or HIPAA, which focus on protecting personal and sensitive information.

However, denial of service conditions can indirectly affect availability requirements in some regulatory frameworks, but there is no specific information indicating a direct compliance impact from this vulnerability.

The vulnerability arises from processing specially crafted EFI device path nodes with an invalid Length field less than 4 bytes, causing infinite recursion and a process crash.

There are no specific detection commands or network-based detection methods provided in the available information.

The suggested fix is to update the libefiboot component to include a guard clause in the device path node parser that checks if the node length is less than 4 bytes and returns an error to prevent infinite recursion.

Specifically, the fix involves adding a check such as: if (dp->length < 4) return -1;

Therefore, immediate mitigation steps include applying patches or updates from the upstream efivar project or your Linux distribution that address this issue.

This vulnerability exists in libefiboot, a part of the efivar component used for EFI variable handling on Linux systems. The flaw is in the device path node parser, which does not properly check that the Length field of each device path node is at least 4 bytes, the minimum size required for an EFI device path node header.

A local user can exploit this by providing a specially crafted device path node with a Length field smaller than 4 bytes. This causes infinite recursion between two functions, leading to stack exhaustion, a stack overflow, and ultimately crashing the process.

The impact of this vulnerability is a denial of service (DoS) condition. When exploited, it causes the affected process to crash due to stack exhaustion from infinite recursion.

This means that a local user could cause the efivar component or related processes to stop functioning, potentially disrupting system operations that rely on EFI variable handling.

Specifically, the fix involves adding a check like: if (dp->length < 4) return -1; in the parser code.

Therefore, immediate mitigation steps include applying patches or updates from your Linux distribution or the upstream efivar project that address this issue.

The vulnerability described is a denial of service (DoS) issue caused by infinite recursion leading to a process crash. It does not involve unauthorized access, data leakage, or modification of sensitive information.

As such, there is no direct indication from the provided information that this vulnerability impacts compliance with common standards and regulations like GDPR or HIPAA, which primarily focus on protecting personal data confidentiality, integrity, and availability.

However, denial of service could indirectly affect availability requirements under these regulations if exploited in a critical environment, but no explicit compliance impact is detailed in the provided resources.

This vulnerability is related to the libefiboot library used in EFI variable handling on Linux systems and involves a flaw in the device path node parser. Detection would involve checking for the presence of the vulnerable efivar/libefiboot versions on your system.

Since the vulnerability is triggered by processing a specially crafted device path node, direct network detection is not applicable. Instead, detection can focus on verifying the installed package versions or monitoring for crashes related to efivar processes.

Suggested commands to detect if the vulnerable component is present include checking the installed efivar package version, for example:

• rpm -q efivar
• dpkg -l | grep efivar

Additionally, monitoring system logs for crashes or stack overflow errors related to efivar or libefiboot processes may help identify exploitation attempts.

The immediate mitigation step is to update the efivar and libefiboot packages to versions that include the fix for this vulnerability.

The fix involves adding a guard clause in the device path node parser to check if the node length is less than 4 bytes and return an error to prevent infinite recursion and stack exhaustion.

If an update is not immediately available, restricting local user access to the vulnerable components or disabling EFI variable handling features that use libefiboot may reduce risk.

Monitoring for unusual crashes of efivar-related processes and applying security best practices for local user permissions are also recommended.

There is no specific information provided about detection methods or commands to identify this vulnerability on a network or system.

To mitigate this vulnerability, the suggested fix is to update the libefiboot component to include a guard clause in the device path node parser that checks if the node length is less than 4 bytes and returns an error to prevent infinite recursion.

• Apply patches or updates from your Linux distribution that address this issue in the efivar/libefiboot library.
• Ensure that the parser includes a check similar to: if (dp->length < 4) return -1;
• Avoid processing untrusted or specially crafted EFI device path nodes that could trigger the vulnerability.
