CVE-2025-54886
Description
A flaw was found in skops. The Card.get_model function allows arbitrary code execution due to a lack of input validation, allowing a local attacker to trigger this vulnerability. This issue occurs when processing a malicious job file, leading to potential arbitrary code execution on the affected system.
Statement
The severity of this vulnerability is rated Moderate, as it does not impact system availability. The effects are confined to the application layer, without compromising the underlying system stability.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Understanding the Weakness (CWE)
Integrity
Technical Impact: Modify Application Data; Unexpected State
Attackers can modify unexpected objects or data that was assumed to be safe from modification. Deserialized data or code could be modified without using the provided accessor functions, or unexpected functions could be invoked.
Availability
Technical Impact: DoS: Resource Consumption (CPU)
If a function is making an assumption on when to terminate, based on a sentry in a string, it could easily never terminate.
Other
Technical Impact: Varies by Context
The consequences can vary widely, because it depends on which objects or methods are being deserialized, and how they are used. Making an assumption that the code in the deserialized object is valid is dangerous and can enable exploitation. One example is attackers using gadget chains to perform unauthorized actions, such as generating a shell.
