AI-Generated

A vulnerability in the Linux kernel's AMD KFD debugger allows for an integer overflow in the `get_queue_ids()` function, potentially leading to memory corruption on 32-bit systems. This could be exploited to cause denial of service or potentially execute arbitrary code, making it critical for organizations using affected Linux distributions to prioritize patching. System administrators and security teams managing Linux environments, especially those utilizing AMD hardware, should address this issue promptly to mitigate risks.

Original NVD Description

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: fix a vulnerability of integer overflow in kfd debugger get_queue_ids() computes array_size = num_queues * sizeof(uint32_t), which could overflow on 32-bit size_t build. using array_size() instead, it saturates to SIZE_MAX on overflow. (cherry picked from commit 2d57a0475f085c08b49312dfd8edcb461845f285)
