      "title": "drm/amdgpu: Limit BO list entry count to prevent resource exhaustion",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdgpu: Limit BO list entry count to prevent resource exhaustion\n\nUserspace can pass an arbitrary number of BO list entries via the\nbo_number field. Although the previous multiplication overflow check\nprevents out-of-bounds allocation, a large number of entries could still\ncause excessive memory allocation (up to potentially gigabytes) and\nunnecessarily long list processing times.\n\nIntroduce a hard limit of 128k entries per BO list, which is more than\nsufficient for any realistic use case (e.g., a single list containing all\nbuffers in a large scene). This prevents memory exhaustion attacks and\nensures predictable performance.\n\nReturn -EINVAL if the requested entry count exceeds the limit\n\n(cherry picked from commit 688b87d39e0aa8135105b40dc167d74b5ada5332)",
