Description

This vulnerability in AX53 v1, AX55 v4 and AX55 v4.6 results from insufficient input sanitization in the device’s probe handling logic, where unvalidated parameters can trigger a stack-based buffer overflow that causes the affected service to crash and, under specific conditions, may enable remote code execution through complex heap-spray techniques. Successful exploitation may result in repeated service unavailability and, in certain scenarios, allow an attacker to gain control of the device.

• CWE-121Stack-based Buffer OverflowA 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).
