"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdgpu: fix zero-size GDS range init on RDNA4\n\nRDNA4 (GFX 12) hardware removes the GDS, GWS, and OA on-chip memory\nresources. The gfx_v12_0 initialisation code correctly leaves\nadev->gds.gds_size, adev->gds.gws_size, and adev->gds.oa_size at\nzero to reflect this.\n\namdgpu_ttm_init() unconditionally calls amdgpu_ttm_init_on_chip() for\neach of these resources regardless of size. When the size is zero,\namdgpu_ttm_init_on_chip() forwards the call to ttm_range_man_init(),\nwhich calls drm_mm_init(mm, 0, 0). drm_mm_init() immediately fires\nDRM_MM_BUG_ON(start + size <= start) -- trivially true when size is\nzero -- crashing the kernel during modprobe of amdgpu on an RX 9070 XT.\n\nGuard against this by returning 0 early from\namdgpu_ttm_init_on_chip() when size_in_page is zero. This skips TTM\nresource manager registration for hardware resources that are absent,\nwithout affecting any other GPU type.\n\nDRM_MM_BUG_ON() only asserts if CONFIG_DRM_DEBUG_MM is enabled in\nthe kernel config. This is apparently rarely enabled as these chips\nhave been in the market for over a year and this issue was only reported\nnow.\n\nOops-Analysis: http://oops.fenrus.org/reports/bugzilla.korg/221376/report.html\n(cherry picked from commit 5719ce5865279cad4fd5f01011fe037168503f2d)"
