A stack buffer overflow has been identified in the AsIO3.sys driver. This vulnerability can be triggered by input manipulation, may leading to a system crash (BSOD) or other potentially undefined execution. Refer to the 'Security Update for Armoury Crate App' section on the ASUS Security Advisory for more information.
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
