CVE-2026-46146

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Avoid potential endless loop in convertchmapv3 The convertchmapv3 has a loop with its increment size of csdesc-wLength, but we forgot to validate csdesc-wLength itself, which may lead to potential endless loop by...

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...

CVE-2026-46018

CVE-2026-46018 is a Linux kernel issue in ALSA: usb-audio (UAC2) where parse_uac2_sample_rate_range() capped at MAX_NR_RATES but only broke the inner loop; a malformed UAC2 RANGE could continue parsing and flood with "invalid uac2 rates". The fix stops the whole parse at the cap and returns the c...
