CVE-2026-46184

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> sound: ua101: fix division by zero at probe<br /> <br /> Add a missing sanity check for bNrChannels in detect_usb_format()<br /> to prevent a division by zero in playback_urb_complete() and<br /> capture_urb_complete().<br /> <br /> USB core does not validate class-specific descriptor fields such<br /> as bNrChannels, so drivers must verify them before use. If a<br /> device provides bNrChannels = 0, frame_bytes becomes zero and is<br /> later used as a divisor in the URB completion handlers, leading<br /> to a kernel crash.
