The parseinstruction function in gallium/auxiliary/tgsi/tgsitext.c in virglrenderer before 0.6.0 allows local guest OS users to cause a denial of service (out-of-bounds array access and process crash) via a crafted texture instruction.

The utilformatispureuint function in vrendrenderer.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 VIRGLCCMDCLEAR command.

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

Stack-based buffer overflow in the parseidentifier function in tgsitext.c in the TGSI auxiliary module in the Gallium driver 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 related to parsing properties.

The vrenddecodereset function in vrenddecode.c in virglrenderer before 0.6.0 allows local guest OS users to cause a denial of service (NULL pointer dereference and QEMU process crash) by destroying context 0 (zero).

Memory leak in the addshaderprogram function in vrendrenderer.c in virglrenderer before 0.6.0 allows local guest OS users to cause a denial of service (host memory consumption) via vectors involving the sprog variable.

Heap-based buffer overflow in the vrendcreatevertexelementsstate function in vrendrenderer.c in virglrenderer before 0.6.0 allows local guest OS users to cause a denial of service (out-of-bounds array access and crash) via the numelements parameter.

The vrenddrawvbo 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 vertextbufferindex.
