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.\n\n## Affected\n\n- `Linux >= 16845c5d540929d2f4dc845f11fbbb238e69170a < 977c2934064969503cabf98b1135d202ff62822e`\n- `Linux >= 16845c5d540929d2f4dc845f11fbbb238e69170a < 5118b5fdf1eb9922a0cdd2afd25252081e2d4302`\n- `Linux >= 16845c5d540929d2f4dc845f11fbbb238e69170a < a9bb8f8fd5694185c2f71ff91869afb300aab392`\n- `Linux >= 16845c5d540929d2f4dc845f11fbbb238e69170a < 03bdbf182082694ab2add620d85f1a8b8f51bbbc`\n- `Linux >= 16845c5d540929d2f4dc845f11fbbb238e69170a < 5c2cb3dd1447752b73d4f44d6b7434bc5259bfec`\n- `Linux >= 16845c5d540929d2f4dc845f11fbbb238e69170a < 7c8deb77d05bcc8f79e255f669d82ec6ce91be12`\n- `Linux >= 16845c5d540929d2f4dc845f11fbbb238e69170a < 036d28db1818af2f9d80db771f5405da84d7732d`\n- `Linux 5.11`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
