This commit replaces the static\narray allocation with dynamic memory allocation using `kcalloc`,\nthereby reducing the stack size.\n\nThis change avoids the risk of stack overflows in kernel space,  in\nscenarios where `AMDGPU_MAX_QUEUES` is large. The  allocated memory is\nfreed using `kfree` before the function returns  to prevent memory\nleaks.\n\nFixes the below with gcc W=1:\ndrivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_process.c: In function ‘kfd_get_cu_occupancy’:\ndrivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_process.c:322:1: warning: the frame size of 1056 bytes is larger than 1024 bytes [-Wframe-larger-than=]\n  322 | }\n      | ^","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-787"],"references":["https://git.kernel.org/stable/c/6d9f07196389f35a3afebcf1a12c1425725caddd","https://git.kernel.org/stable/c/922f0e00017b09d9d47e3efac008c8b20ed546a0"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:57:56.913276502+00:00"},"epss":{"cve":"CVE-2024-56695","score":0.00215,"percentile":0.11951,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
