FAUCET Score

CVE-2025-38438 is a memory leak vulnerability in the Linux kernel's ASoC SOF Intel HDA audio driver. Specifically, it involves the sof_pdata->tplg_filename variable, which can be allocated using kstrdup() and then overwritten, leading to unreferenced memory. This vulnerability affects Linux kernel versions. Rated as MEDIUM severity with a CVSS score of 5.5, the vulnerability has a local attack vector and low attack complexity, requiring local user privileges. While it does not impact confidentiality or integrity, it can lead to high availability impact due to resource exhaustion from the memory leak.
