CVE-2024-53150 is an out-of-bounds read in the Linux kernel ALSA USB-audio driver's clock-source discovery logic. While traversing USB audio clock descriptors, the driver did not validate each descriptor's bLength field. A malicious USB audio device can supply an undersized clock descriptor, causing the kernel to read beyond the descriptor boundary. The upstream fix adds descriptor-length validation and skips descriptors that are shorter than required. It validates clock-source and clock-multiplier descriptors against their expected structure sizes and performs additional bounds checks for variable-length UAC2 and UAC3 clock-selector descriptors.
