Vulnerability from fkie_nvd - Published: 2026-05-27 14:17 - Updated: 2026-06-17 10:52
Severity
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix memory leak in amdgpu_acpi_enumerate_xcc() In amdgpu_acpi_enumerate_xcc(), if amdgpu_acpi_dev_init() returns -ENOMEM, the function returns directly without releasing the allocated xcc_info, resulting in a memory leak. Fix this by ensuring that xcc_info is properly freed in the error paths. Compile tested only. Issue found using a prototype static analysis tool and code review.
