Security researcher Holger Fuhrmannek used the used the Address Sanitizer tool to discover an out-of-bounds read issue with Web Audio when interacting with custom waveforms with invalid values. This results in a crash and could allow for the reading of random memory which may contain sensitive data, or of memory addresses that could be used in combination with another bug.
