  "summary": "drm/amdkfd: Clear VRAM on allocation to prevent stale data exposure",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdkfd: Clear VRAM on allocation to prevent stale data exposure\n\nKFD VRAM allocations set AMDGPU_GEM_CREATE_VRAM_WIPE_ON_RELEASE\nbut not AMDGPU_GEM_CREATE_VRAM_CLEARED, leaving freshly allocated\nVRAM with stale data from prior use observable by compute kernels.\n\nThe GEM ioctl path already sets VRAM_CLEARED for all userspace\nallocations via amdgpu_gem_create_ioctl() and\namdgpu_mode_dumb_create(). The KFD path was missing this flag,\nallowing stale page table remnants to leak into user buffers.\n\nThis causes crashes in RCCL P2P transport where non-zero data in\nptrExchange/head/tail fields corrupts the protocol handshake.",
