"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdkfd: wq_release signals dma_fence only when available\n\nkfd_process_wq_release() signals eviction fence by\ndma_fence_signal() which wanrs if dma_fence\nis NULL.\n\nkfd_process->ef is initialized by kfd_process_device_init_vm()\nthrough ioctl. That means the fence is NULL for a new\ncreated kfd_process, and close a kfd_process right\nafter open it will trigger the warning.\n\nThis commit conditionally signals the eviction fence\nin kfd_process_wq_release() only when it is available.\n\n[ 503.660882] WARNING: CPU: 0 PID: 9 at drivers/dma-buf/dma-fence.c:467 dma_fence_signal+0x74/0xa0\n[ 503.782940] Workqueue: kfd_process_wq kfd_process_wq_release [amdgpu]\n[ 503.789640] RIP: 0010:dma_fence_signal+0x74/0xa0\n[ 503.877620] Call Trace:\n[ 503.880066] <TASK>\n[ 503.882168] ? __warn+0xcd/0x260\n[ 503.885407] ? dma_fence_signal+0x74/0xa0\n[ 503.889416] ? report_bug+0x288/0x2d0\n[ 503.893089] ? handle_bug+0x53/0xa0\n[ 503.896587] ? exc_invalid_op+0x14/0x50\n[ 503.900424] ? asm_exc_invalid_op+0x16/0x20\n[ 503.904616] ? dma_fence_signal+0x74/0xa0\n[ 503.908626] kfd_process_wq_release+0x6b/0x370 [amdgpu]\n[ 503.914081] process_one_work+0x654/0x10a0\n[ 503.918186] worker_thread+0x6c3/0xe70\n[ 503.921943] ? srso_alias_return_thunk+0x5/0xfbef5\n[ 503.926735] ? srso_alias_return_thunk+0x5/0xfbef5\n[ 503.931527] ? __kthread_parkme+0x82/0x140\n[ 503.935631] ? __pfx_worker_thread+0x10/0x10\n[ 503.939904] kthread+0x2a8/0x380\n[ 503.943132] ? __pfx_kthread+0x10/0x10\n[ 503.946882] ret_from_fork+0x2d/0x70\n[ 503.950458] ? __pfx_kthread+0x10/0x10\n[ 503.954210] ret_from_fork_asm+0x1a/0x30\n[ 503.958142] </TASK>\n[ 503.960328] ---[ end trace 0000000000000000 ]---\n\n(cherry picked from commit 2774ef7625adb5fb9e9265c26a59dca7b8fd171e)"
