Description
CVE-2025-71286 is a high-severity vulnerability in the Linux kernel's ASoC SOF ipc4-topology component. It involves incorrect allocation size for bytes controls, which could lead to memory corruption issues. The flaw was fixed by adjusting the allocation to properly account for the full size of control data. The vulnerability affects Linux kernel version 6.4.
