Title
drm/amdgpu: Add a lock when accessing the buddy trim function
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Add a lock when accessing the buddy trim function When running YouTube videos and Steam games simultaneously, the tester found a system hang / race condition issue with the multi-display configuration setting. Adding a lock to the buddy allocator's trim function would be the solution. <log snip> [ 7197.250436] general protection fault, probably for non-canonical address 0xdead000000000108 [ 7197.250447] RIP: 0010:__alloc_range+0x8b/0x340 [amddrm_buddy] [ 7197.250470] Call Trace: [ 7197.250472] <TASK> [ 7197.250475] ? show_regs+0x6d/0x80 [ 7197.250481] ? die_addr+0x37/0xa0 [ 7197.250483] ? exc_general_protection+0x1db/0x480 [ 7197.250488] ? drm_suballoc_new+0x13c/0x93d [drm_suballoc_helper] [ 7197.250493] ? asm_exc_general_protection+0x27/0x30 [ 7197.250498] ? __alloc_range+0x8b/0x340 [amddrm_buddy] [ 7197.250501] ? __alloc_range+0x109/0x340 [amddrm_buddy] [ 7197.250506] amddrm_buddy_block_trim+0x1b5/0x260 [amddrm_buddy] [ 7197.250511] amdgpu_vram_mgr_new+0x4f5/0x590 [amdgpu] [ 7197.250682] amdttm_resource_alloc+0x46/0xb0 [amdttm] [ 7197.250689] ttm_bo_alloc_resource+0xe4/0x370 [amdttm] [ 7197.250696] amdttm_bo_validate+0x9d/0x180 [amdttm] [ 7197.250701] amdgpu_bo_pin+0x15a/0x2f0 [amdgpu] [ 7197.250831] amdgpu_dm_plane_helper_prepare_fb+0xb2/0x360 [amdgpu] [ 7197.251025] ? try_wait_for_completion+0x59/0x70 [ 7197.251030] drm_atomic_helper_prepare_planes.part.0+0x2f/0x1e0 [ 7197.251035] drm_atomic_helper_prepare_planes+0x5d/0x70 [ 7197.251037] drm_atomic_helper_commit+0x84/0x160 [ 7197.251040] drm_atomic_nonblocking_commit+0x59/0x70 [ 7197.251043] drm_mode_atomic_ioctl+0x720/0x850 [ 7197.251047] ? __pfx_drm_mode_atomic_ioctl+0x10/0x10 [ 7197.251049] drm_ioctl_kernel+0xb9/0x120 [ 7197.251053] ? srso_alias_return_thunk+0x5/0xfbef5 [ 7197.251056] drm_ioctl+0x2d4/0x550 [ 7197.251058] ? __pfx_drm_mode_atomic_ioctl+0x10/0x10 [ 7197.251063] amdgpu_drm_ioctl+0x4e/0x90 [amdgpu] [ 7197.251186] __x64_sys_ioctl+0xa0/0xf0 [ 7197.251190] x64_sys_call+0x143b/0x25c0 [ 7197.251193] do_syscall_64+0x7f/0x180 [ 7197.251197] ? srso_alias_return_thunk+0x5/0xfbef5 [ 7197.251199] ? amdgpu_display_user_framebuffer_create+0x215/0x320 [amdgpu] [ 7197.251329] ? drm_internal_framebuffer_create+0xb7/0x1a0 [ 7197.251332] ? srso_alias_return_thunk+0x5/0xfbef5 (cherry picked from commit 3318ba94e56b9183d0304577c74b33b6b01ce516)

No network or adjacent-network exposure exists.\nAC:L - The attacker controls both sides of the race \u2014 one thread repeatedly allocates GFX12-DCC contiguous VRAM buffers driving the unlocked drm_buddy_block_trim(), while other threads hammer ordinary VRAM alloc/free through the locked buddy path \u2014 so the window can be hit reliably by simply looping. The original report shows it triggering under two ordinary concurrent workloads with no attacker effort at all.\nPR:L - DRM_IOCTL_AMDGPU_GEM_CREATE is DRM_AUTH|DRM_RENDER_ALLOW and accepts AMDGPU_GEM_CREATE_GFX12_DCC directly, and amdgpu_cs_find_mapping() forces AMDGPU_GEM_CREATE_VRAM_CONTIGUOUS from the equally unprivileged CS ioctl \u2014 so an ordinary local user with render-node access (the logged-in desktop user, or any process in the render/video group) can reach it without DRM master or any capability.\nUI:N - A single attacker process spawns both the DCC-allocating thread and the concurrent VRAM alloc/free threads; no action by another user is required.\nS:U - The corruption is confined to the kernel\u0027s own drm_buddy allocator state and slab objects within the same kernel security authority; no hypervisor, IOMMU, or DMA isolation boundary is crossed.\nC:H - Free-list corruption yields a use-after-free on kmem_cache-backed drm_buddy_block objects whose contents the attacker can groom via their own VRAM allocations, and double-allocation of the same VRAM range to two different DRM clients allows reading another process\u0027s GPU buffer contents (framebuffers, decoded video, compute data).\nI:H - The racing list_del()/list_insert_sorted()/split_block() sequences give a controlled linked-list write primitive over freed and live buddy blocks, and aliased VRAM lets the attacker overwrite another client\u0027s buffers \u2014 memory corruption of this class is leveragable into arbitrary kernel write and control-flow hijack.\nA:H - The bug was reported as a system hang and reproduced as a general protection fault on LIST_POISON (0xdead000000000108) in __alloc_range, i.e. a hard kernel oops that an unprivileged local user can trigger repeatedly."
