  "details": "In the Linux kernel, the following vulnerability has been resolved:  drm/amd/display: Fix NULL pointer dereference in amdgpu_dm_crtc_set_vblank()  amdgpu_dm_crtc_set_vblank() dereferences acrtc_state-\u003estream when vblank is enabled/queried from DRM_IOCTL_MODE_CRTC_GET_SEQUENCE before a stream is attached to it.  BUG: kernel NULL pointer dereference, address: 0000000000000008 RIP: amdgpu_dm_crtc_set_vblank+0x6b/0x4d0 [amdgpu] Call Trace:  drm_vblank_enable  drm_vblank_get  drm_crtc_get_sequence_ioctl  drm_ioctl_kernel  drm_ioctl  Reproduced by running VKCTS with WSI tests enabled on RADV.  Guard the enable path on acrtc_state-\u003estream being non-NULL, matching the existing checks in this function.  (cherry picked from commit 7b1b31bf6942e6f43509b48da23f8e27269aac39)",
