drivers/soc/qcom/qdsp6v2/voicesvc.c in the QDSP6v2 Voice Service driver for the Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, allows attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a write request, as demonstrated by a voicesvcsendreq buffer overflow.

Multiple integer overflows in the MDSS driver for the Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, allow attackers to cause a denial of service or possibly have unspecified other impact via a large size value, related to mdsscompatutils.c, mdssfb.c, and mdssrotator.c.

The vfe31procgeneral function in drivers/media/video/msm/vfe/msmvfe31.c in the MSM-VFE31 driver for the Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, does not validate a certain id value, which allows attackers to gain privileges or cause a denial of service (memory corruption) via an application that makes a crafted ioctl call.

drivers/gpu/msm/kgsl.c in the MSM graphics driver (aka GPU driver) for the Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, mishandles the KGSLMEMFLAGSGPUREADONLY flag, which allows attackers to gain privileges by leveraging accidental read-write mappings, aka Qualcomm internal bug CR988993.
