CVE-2023-53444 drm/ttm: fix bulk_move corruption when adding a entry

In the Linux kernel, the following vulnerability has been resolved: drm/ttm: fix bulkmove corruption when adding a entry When the resource is the first in the bulkmove range, adding it again thus moving it to the tail will corrupt the list since the first pointer is not moved. This eventually lea...

CVE-2022-50390

The CVE-2022-50390 issue is in the Linux kernel DRM TTM code. It fixes an undefined behavior when shifting a signed 32-bit value by 31 bits in TTM_TT_FLAG_PRIV_POPULATED, by changing the operation to unsigned to avoid UBSAN/shift-out-of-bounds warnings observed during framebuffer/VM operations. T...
