Detailsinfo

A vulnerability, which was classified as critical, has been found in Linux Kernel up to 6.6.139/6.12.87/6.18.29/7.0.6. Affected by this issue is an unknown code block of the component ASoC. The manipulation with an unknown input leads to a divide by zero vulnerability. Using CWE to declare the problem leads to CWE-369. The product divides a value by zero. Impacted is availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: Don't allow pointer operations on unconfigured streams When reporting the pointer for a compressed stream we report the current I/O frame position by dividing the position by the number of channels multiplied by the number of container bytes. These values default to 0 and are only configured as part of setting the stream parameters so this allows a divide by zero to be configured. Validate that they are non zero, returning an error if not

The advisory is shared for download at git.kernel.org. This vulnerability is handled as CVE-2026-46179 since 05/13/2026. There are neither technical details nor an exploit publicly available.
