CVE-2025-48754 is a vulnerability identified in version 0.1.0 of the memory_pages crate, a Rust library developed by FractalFir. The issue is classified under CWE-369, which corresponds to a divide-by-zero error. Specifically, the vulnerability arises when the code performs a division operation without validating the divisor, potentially leading to a division by zero. This can cause the affected application to crash or behave unpredictably, resulting in a denial of service (DoS) condition. The vulnerability has a CVSS v3.1 base score of 2.9, indicating a low severity level. The vector string (CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L) shows that the attack vector is local (AV:L), requires high attack complexity (AC:H), no privileges (PR:N), no user interaction (UI:N), unchanged scope (S:U), and impacts only availability (A:L) without affecting confidentiality or integrity. There are no known exploits in the wild, and no patches have been published yet. The vulnerability is limited to the initial release version 0.1.0 of the memory_pages crate, which is used in Rust-based applications that manage memory page operations. The divide-by-zero error could be triggered by malformed or unexpected input parameters passed to the library functions, causing the application to terminate unexpectedly or enter an unstable state. While this does not directly lead to data leakage or code execution, the availability impact could disrupt services relying on this crate.

For European organizations, the impact of this vulnerability is primarily related to service availability. Applications using the vulnerable memory_pages crate could experience crashes or interruptions if the divide-by-zero condition is triggered. This could affect internal tools, backend services, or any Rust-based applications that depend on this library for memory management. Although the severity is low, critical systems with high availability requirements could face operational disruptions. The lack of confidentiality or integrity impact reduces the risk of data breaches or unauthorized modifications. However, organizations in sectors such as finance, healthcare, or critical infrastructure that rely on Rust applications might see degraded service quality or downtime. Since exploitation requires local access and high attack complexity, remote attackers are unlikely to exploit this vulnerability directly. Nonetheless, insider threats or compromised local accounts could potentially trigger the fault. The absence of user interaction and privileges required simplifies exploitation in trusted environments but limits the scope to local attackers.

To mitigate this vulnerability, European organizations should first identify any usage of the memory_pages crate version 0.1.0 within their Rust applications. Developers should audit code paths that interact with this crate to ensure input validation is robust and that division operations are protected against zero divisors. Until an official patch is released, organizations can implement defensive programming techniques such as pre-checking divisor values before division or wrapping calls to the crate in error-handling constructs to gracefully manage potential panics. Additionally, restricting local access to trusted users and enforcing strict access controls can reduce the risk of exploitation. Monitoring application logs for crashes or abnormal terminations related to memory_pages usage can help detect attempted exploitation. Organizations should also track updates from the vendor or Rust community for patches or newer crate versions addressing this issue and plan timely upgrades once available. Incorporating fuzz testing and static analysis tools focused on arithmetic operations can proactively identify similar vulnerabilities in Rust codebases.
