CVE-2026-46146 Details
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.
A vulnerability in the Linux kernel's ALSA USB-Audio subsystem could lead to a potential endless loop in the 'convert_chmap_v3()' function. This issue arises because the function's loop increment is based on 'cs_desc->wLength', which is not properly validated. A malformed descriptor could exploit this oversight, causing the loop to run indefinitely. The vulnerability affects the Linux kernel stable tree.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. The specific commit that resolves this issue is '4e0ee232ebe3df04874125d7c7f3e6c25ea5483d', which is available in the Linux kernel stable tree.
