Windows crash via undisclosed stack overflow

Published Apr 30, 2026 · Updated Apr 30, 2026

Stack-based buffer overflow in Absolute Secure Access Windows client before 14.50 allows local users to crash Windows with a blue screen. Absolute has not disclosed the affected client component, the input that reaches it, or the unchecked operation that overruns the stack buffer. Exploitation requires local control of the client; the disclosed outcome is an operating-system crash, while the vendor does not explain the low integrity effect represented in its score.
