Detailsinfo

A vulnerability, which was classified as critical, has been found in Linux Kernel up to 6.0.15/6.1.1. Affected by this issue is the function memcpy_fromio of the component ASoC. The manipulation with an unknown input leads to a buffer overflow vulnerability. Using CWE to declare the problem leads to CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. Impacted is confidentiality, integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: ASoC: Intel: avs: Fix potential RX buffer overflow If an event caused firmware to return invalid RX size for LARGE_CONFIG_GET, memcpy_fromio() could end up copying too many bytes. Fix by utilizing min_t().

The advisory is available at git.kernel.org. This vulnerability is handled as CVE-2022-50325 since 09/15/2025. The exploitation is known to be easy. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 01/10/2026).
