Description
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: unmap and remove csa_va properly Root PD BO should be reserved before unmap and remove a bo_va from VM otherwise lockdep will complain. v2: check fpriv->csa_va is not NULL instead of amdgpu_mcbp (christian) [14616.936827] WARNING: CPU: 6 PID: 1711 at drivers/gpu/drm/amd/amdgpu/amdgpu_vm.c:1762 amdgpu_vm_bo_del+0x399/0x3f0 [amdgpu] [14616.937096] Call Trace: [14616.937097] <TASK> [14616.937102] amdgpu_driver_postclose_kms+0x249/0x2f0 [amdgpu] [14616.937187] drm_file_free+0x1d6/0x300 [drm] [14616.937207] drm_close_helper.isra.0+0x62/0x70 [drm] [14616.937220] drm_release+0x5e/0x100 [drm] [14616.937234] __fput+0x9f/0x280 [14616.937239] ____fput+0xe/0x20 [14616.937241] task_work_run+0x61/0x90 [14616.937246] exit_to_user_mode_prepare+0x215/0x220 [14616.937251] syscall_exit_to_user_mode+0x2a/0x60 [14616.937254] do_syscall_64+0x48/0x90 [14616.937257] entry_SYSCALL_64_after_hwframe+0x63/0xcd
A vulnerability in the Linux kernel's AMD GPU driver has been addressed, concerning the management of Command Stream Address (CSA) Virtual Address (VA) during the unmapping process. The issue arose because the Root Page Directory Buffer Object (PD BO) was not properly reserved before unmapping and removing a buffer object virtual address from the virtual memory, leading to potential inconsistencies. This vulnerability was identified in the AMDGPU component of the Direct Rendering Manager (DRM) in the Linux kernel.
Users can apply the latest updates from the Linux kernel stable tree to address this vulnerability.
