En bref Sévérité Non disponible EPSS EPSS 0.13 % · centile 3 (2026-10-27) État PUBLISHED Publiée 2026-05-28 Mise à jour 2026-10-15 Attribuée par Linux Statut NVD Modified
Description In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Avoid potential endless loop in convert_chmap_v3()
The convert_chmap_v3() has a loop with its increment size of
cs_desc->wLength, but we forgot to validate cs_desc->wLength itself,
which may lead to potential endless loop by a malformed descriptor.
Add a proper size check to abort the loop for plugging the hole.
