Use-After-Free Vulnerability in Intel ASoC Components in Linux Kernel

CVE-2025-40338

What is CVE-2025-40338?

A vulnerability in the Linux kernel's ASoC (ALSA System on Chip) subsystem allows components to share a name pointer directly, leading to potential use-after-free errors during component teardown. To mitigate this issue, the name should be duplicated to prevent sharing, which can cause unexpected behavior or crashes in the kernel. The vulnerability highlights the importance of careful management of memory and component initialization in the kernel.
