CVE-2026-46146

CVE-2026-46146 affects the Linux kernel's ALSA USB audio stack, specifically the convert_chmap_v3() routine. A loop uses cs_desc->wLength for increment but this value isn’t validated, allowing a potential endless loop with malformed descriptors. The issue is resolved by adding a proper size ch...
