Last modified

CVE-2025-68346 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: ALSA: dice: fix buffer overflow in detect_stream_formats() The function detect_stream_formats() reads the stream_count value directly from a FireWire device without validating it. This can lead to out-of-bounds writes when a malicious device provides a stream_count value greater than MAX_STREAMS. Fix by applying the same validation to both TX and RX stream counts in detect_stream_formats().. EPSS estimates a 0.20% chance of exploitation in the next 30 days.
