CVE-2024-50282 is a high-severity vulnerability identified in the Linux kernel, specifically within the AMDGPU driver component responsible for managing AMD graphics hardware. The flaw resides in the function amdgpu_debugfs_gprwave_read(), which is part of the debug filesystem interface for AMD GPU wave data. The vulnerability is a buffer overflow caused by a missing size check when reading data; if the requested size exceeds 4KB, the function may write beyond the allocated buffer boundaries. This type of vulnerability is classified under CWE-120 (Classic Buffer Overflow), which can lead to memory corruption. Exploitation of this flaw requires local privileges (AV:L - Attack Vector: Local) and low complexity (AC:L - Attack Complexity: Low) with low privileges (PR:L - Privileges Required: Low) and no user interaction (UI:N). The impact is critical as it affects confidentiality, integrity, and availability (C:H/I:H/A:H), potentially allowing an attacker to execute arbitrary code with kernel privileges, cause system crashes, or escalate privileges. The vulnerability was patched by adding the missing size check to prevent buffer overflow conditions. No known exploits are currently reported in the wild, but the high CVSS score of 7.8 indicates a significant risk if left unpatched. The affected Linux kernel versions include those identified by the commit hash 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2, indicating recent kernel releases prior to the patch are vulnerable. This vulnerability is particularly relevant for systems running AMD GPUs on Linux, including servers, desktops, and embedded devices using the affected kernel versions.

For European organizations, this vulnerability poses a serious threat, especially those relying on Linux-based infrastructure with AMD GPU hardware. The potential for local attackers or malicious insiders to exploit this flaw to gain elevated privileges or execute arbitrary code in kernel space could lead to full system compromise, data breaches, or denial of service. Critical sectors such as finance, healthcare, government, and industrial control systems that utilize Linux servers or workstations with AMD GPUs are at risk. The vulnerability could also affect cloud service providers and data centers in Europe that deploy Linux virtual machines with AMD GPU passthrough or acceleration. Given the high impact on confidentiality, integrity, and availability, exploitation could disrupt business operations, lead to data loss, or expose sensitive information. The absence of known exploits in the wild currently reduces immediate risk, but the ease of exploitation and severity warrant urgent patching to prevent future attacks.

European organizations should prioritize updating their Linux kernels to the latest patched versions that include the fix for CVE-2024-50282. Specifically, ensure that the kernel version includes the commit f5d873f5825b40d886d03bd2aede91d4cf002434 or later. Systems with AMD GPUs should be audited to confirm the presence of the vulnerable amdgpu driver version. Employ strict access controls to limit local user privileges, minimizing the risk of exploitation by low-privileged users. Implement kernel-level security modules such as SELinux or AppArmor to restrict access to debugfs interfaces and sensitive kernel components. Monitoring and logging of local user activities related to GPU debug interfaces can help detect suspicious behavior. For environments where immediate patching is not feasible, consider disabling or restricting access to the amdgpu debugfs interfaces as a temporary mitigation. Additionally, maintain up-to-date intrusion detection systems capable of identifying anomalous kernel-level activities. Regular vulnerability scanning and compliance checks should include verification of kernel patch levels related to this CVE.
