CVE-2015-4036: n/a vulnerability

CVE-2015-4036: Array index error in the tcm_vhost_make_tpg function in drivers/vhost/scsi.c in the Linux kernel before 4.0...

Array index error in the tcm_vhost_make_tpg function in drivers/vhost/scsi.c in the Linux kernel before 4.0 might allow guest OS users to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted VHOST_SCSI_SET_ENDPOINT ioctl call. NOTE: the affected function was renamed to vhost_scsi_make_tpg before the vulnerability was announced.

Security readout for executives and security teams

CVE-2015-4036 affects the Linux kernel vhost SCSI virtualization code before 4.0. A guest OS user could trigger memory corruption through a vhost SCSI endpoint ioctl, potentially crashing the host kernel or causing unspecified effects. The available sources do not show active exploitation. Exposure is most likely on virtualization hosts running affected Linux kernels before 4.0, or older vendor kernels without the backported fix, where vhost SCSI is enabled or reachable by guest workloads. Treat this as a virtualization host stability and isolation risk. It is not supported by active-exploitation evidence, but affected hosts can carry higher business impact because guest activity may affect host availability. Mitigation focus: Apply vendor kernel updates that include the CVE-2015-4036 fix.; Prioritize virtualization hosts using vhost SCSI or SCSI passthrough features.; Check Ubuntu, SUSE, Red Hat, or distribution-specific advisories for backported fixes..
