Race condition in NVMap in NVIDIA Tegra Linux Kernel 3.10 allows local users to gain privileges via a crafted NVMAP_IOC_CREATE IOCTL call, which triggers a use-after-free error, as demonstrated by using a race condition to escape the Chrome sandbox.
The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.
