The freed object stays in that\ninterval tree, so a later lookup or insertion walks freed memory, and\nthe dma_resv and gpuva lock are never destroyed.\n\nCall drm_gem_object_release() before kfree() on both paths.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
