A time-of-check time-of-use (toctou) race condition exists, which allows an authorized attacker to elevate privileges locally. A TOCTOU race condition occurs when a program checks the state of a resource and then acts upon that resource, but the state changes between the check and the use.

An out-of-bounds read occurs due to insufficient bounds checking, which may allow an application to cause a denial-of-service. An out-of-bounds read is a condition where a program reads data past the end or before the beginning of the intended buffer.
