CVE-2026-46146

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture usb-audio subsystem. This vulnerability exists in the convertchmapv3 function, where the csdesc-wLength value is not properly validated. A malicious actor could provide a specially crafted, malformed USB audio descripto...

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

In the Linux kernel’s ALSA usb-audio driver, the convert_chmap_v3() loop used cs_desc->wLength as the increment without validating the length, which may cause an endless loop on malformed descriptors. A proper size check was added to abort the loop, mitigating the issue. Affected component: Li...
