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