CVE-2026-32677 in gaudi-container-runtime
Summary
by MITRE • 08/11/2026
Path traversal for some gaudi-container-runtime before version 1.24.0 within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires passive user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

This vulnerability represents a critical privilege escalation flaw in gaudi-container-runtime versions prior to 1.24.0, operating within Ring 3 user application contexts. The path traversal vulnerability stems from inadequate input validation and sanitization mechanisms that fail to properly restrict file system access attempts. Attackers can exploit this weakness by crafting malicious paths that bypass normal access controls, allowing them to traverse directory structures and potentially access restricted files or directories. The vulnerability specifically affects container runtime environments where user applications execute with elevated privileges, creating a dangerous attack surface that can be leveraged for unauthorized system access.
The technical implementation of this flaw involves improper handling of file path resolution within the container runtime environment. When user applications attempt to access files through the container runtime interface, insufficient validation allows attackers to manipulate path parameters to navigate beyond intended boundaries. This type of vulnerability aligns with CWE-22 Path Traversal and CWE-73 Path Traversal in User-Controlled File Name or Path categories, which are fundamental security weaknesses that enable unauthorized file system access. The attack vector requires an authenticated user context combined with low complexity exploitation techniques, making it particularly dangerous as it can be executed by adversaries who already have legitimate access to the system.
The operational impact of this privilege escalation vulnerability extends across all three core security principles with high severity implications. Confidentiality is severely compromised as attackers can access sensitive files that should remain protected, potentially exposing system credentials, configuration data, or user information. Integrity suffers significantly since malicious actors can modify critical system files or container runtime components, leading to potential system corruption or persistent backdoor installations. Availability is also threatened as attackers could potentially disrupt container operations or system services through destructive file modifications. The vulnerability's potential to cause cascading failures means that impacts on confidentiality, integrity, and availability can extend beyond immediate system boundaries to affect entire infrastructure deployments.
Mitigation strategies for this vulnerability must address both the immediate runtime patching requirements and broader architectural security improvements. Organizations should immediately upgrade to gaudi-container-runtime version 1.24.0 or later, which includes proper input validation and path sanitization mechanisms. The implementation of strict access control policies within container environments is essential, including mandatory use of secure path resolution functions and comprehensive input filtering for all file system operations. System administrators should also implement privilege separation techniques that limit the scope of user applications and establish robust monitoring for suspicious file system access patterns. Additionally, organizations should consider implementing container runtime security solutions that can detect and prevent malicious path traversal attempts through behavioral analysis and anomaly detection systems. The vulnerability demonstrates the critical importance of secure coding practices in privileged environments and highlights the need for comprehensive security testing throughout the software development lifecycle to prevent similar issues from emerging in other components of containerized infrastructure.
