  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdgpu/userq: fix indefinite fence wait during GPU reset\n\npre_reset only force-completes fences of MAPPED queues. A queue in any\nother state (e.g. mid-eviction) keeps its last_fence pending; after a\nGPU reset that fence never signals, so the eviction/suspend worker and\nprocess teardown (amdgpu_evf_mgr_flush_suspend) wait on it forever and\nwedge the machine:\n\n  INFO: task kworker/6:28 blocked for more than 120 seconds.\n  Workqueue: events amdgpu_eviction_fence_suspend_worker [amdgpu]\n  Call Trace:\n   dma_fence_wait_timeout+0x7e/0x130\n   amdgpu_userq_evict+0x67/0x140 [amdgpu]\n   amdgpu_eviction_fence_suspend_worker+0xd8/0x160 [amdgpu]\n   process_scheduled_works+0xa6/0x420\n\nForce-complete every queue's fence regardless of state. The unmap and\nmark-hung step stays gated on MAPPED, since unmapping a queue that is\nnot mapped is invalid.\n\n(cherry picked from commit 9102b39fa924dcc3dc75a3137bfa9633c40b88c0)",
