CWE-415
 
 
A double-free vulnerability in vrend_renderer.c in virglrenderer through 0.8.1 allows attackers to cause a denial of service by triggering texture allocation failure, because vrend_renderer_resource_allocated_texture is not an appropriate place for a free.

 
 
CVE-2020-8002

CWE-476
 
 
A NULL pointer dereference in vrend_renderer.c in virglrenderer through 0.8.1 allows attackers to cause a denial of service via commands that attempt to launch a grid without previously providing a Compute Shader (CS).

CVE-2019-18391

CWE-787
 
 
A heap-based buffer overflow in the vrend_renderer_transfer_write_iov function in vrend_renderer.c in virglrenderer through 0.8.0 allows guest OS users to cause a denial of service via VIRGL_CCMD_RESOURCE_INLINE_WRITE commands.

 
 
CVE-2019-18390

CWE-125
 
 
An out-of-bounds read in the vrend_blit_need_swizzle function in vrend_renderer.c in virglrenderer through 0.8.0 allows guest OS users to cause a denial of service via VIRGL_CCMD_BLIT commands.

 
 
CVE-2019-18389

CWE-787
 
 
A heap-based buffer overflow in the vrend_renderer_transfer_write_iov function in vrend_renderer.c in virglrenderer through 0.8.0 allows guest OS users to cause a denial of service, or QEMU guest-to-host escape and code execution, via VIRGL_CCMD_RESOURCE_INLINE_WRITE commands.

 
 
CVE-2019-18388

CWE-476
 
 
A NULL pointer dereference in vrend_renderer.c in virglrenderer through 0.8.0 allows guest OS users to cause a denial of service via malformed commands.

CVE-2017-5956

 
 
The vrend_draw_vbo function in virglrenderer before 0.6.0 allows local guest OS users to cause a denial of service (out-of-bounds array access and QEMU process crash) via vectors involving vertext_buffer_index.

 
 
CVE-2016-10214

 
 
Memory leak in the virgl_resource_attach_backing function in virglrenderer before 0.6.0 allows local guest OS users to cause a denial of service (memory consumption) via a large number of VIRTIO_GPU_CMD_RESOURCE_ATTACH_BACKING commands.

CVE-2017-5937

 
 
The util_format_is_pure_uint function in vrend_renderer.c in Virgil 3d project (aka virglrenderer) 0.6.0 and earlier allows local guest OS users to cause a denial of service (NULL pointer dereference) via a crafted VIRGL_CCMD_CLEAR command.

 
 
CVE-2017-6386

CWE-772
 
 
Memory leak in the vrend_create_vertex_elements_state function in vrend_renderer.c in virglrenderer allows local guest OS users to cause a denial of service (host memory consumption) via a large number of VIRGL_OBJECT_VERTEX_ELEMENTS commands.
