CVE-2024-41028 is a vulnerability identified in the Linux kernel, specifically within the platform/x86 subsystem related to the toshiba_acpi driver. The issue arises from improper handling of the toshiba_dmi_quirks[] array, which is used in conjunction with standard Desktop Management Interface (DMI) matching functions. The array is expected to be terminated by an empty entry to prevent out-of-bounds access. However, the missing terminating empty entry causes the kernel to access memory beyond the bounds of the array each time the quirk list is processed. This out-of-bounds access can lead to undefined behavior, including potential kernel crashes or memory corruption. The vulnerability is rooted in a programming logic error rather than a complex exploit chain, and it affects Linux kernel versions identified by the commit hash 3cb1f40dfdc3b9f5449076c96b4e2523139f5cd0. The fix involves adding the missing terminating empty entry to the toshiba_dmi_quirks[] array, thereby preventing the out-of-bounds access. There are no known exploits in the wild at the time of publication, and no CVSS score has been assigned yet. The vulnerability is categorized as a memory safety issue that could impact system stability and security if exploited.

For European organizations, this vulnerability primarily threatens the stability and reliability of Linux systems running on x86 platforms with the affected toshiba_acpi driver. While the vulnerability does not directly indicate privilege escalation or remote code execution, out-of-bounds memory access in kernel space can lead to system crashes (denial of service) or potentially be leveraged by attackers to execute arbitrary code or escalate privileges, depending on the surrounding kernel context and exploit complexity. Organizations relying on Linux servers, workstations, or embedded systems with Toshiba ACPI support could experience unexpected system instability, impacting critical services and operational continuity. The impact is more pronounced in sectors with high Linux adoption such as telecommunications, finance, research institutions, and public sector entities across Europe. Given the kernel-level nature of the vulnerability, any exploitation could compromise system integrity and availability, posing risks to data confidentiality indirectly if systems become unstable or require emergency maintenance. However, the lack of known exploits and the requirement for local code execution or privileged access to trigger the vulnerability reduces the immediate threat level.

European organizations should prioritize updating their Linux kernels to versions that include the patch fixing CVE-2024-41028. Specifically, system administrators should verify if their kernel version corresponds to the affected commit hash and apply the official Linux kernel updates or backported patches from their Linux distribution vendors. For environments where immediate patching is not feasible, organizations should audit and limit access to systems running the affected kernel, especially restricting local user privileges to trusted personnel only. Monitoring kernel logs for unusual ACPI-related errors or crashes can help detect potential exploitation attempts. Additionally, organizations should implement strict change management and vulnerability scanning processes to identify and remediate such kernel-level vulnerabilities promptly. Engaging with Linux distribution security advisories and subscribing to relevant security mailing lists will ensure timely awareness of patches and mitigations. Finally, testing patches in staging environments before deployment can prevent unintended disruptions.
