CVE-2025-38421

HIGH

Linux Kernel 6.12.23-6.12.99, 6.14.0-6.14.99, 6.15.0-6.15.3 - Use-After-Free in AMD PMF Smart PC Setup

Title source: llm

Description

In the Linux kernel, the following vulnerability has been resolved: platform/x86/amd: pmf: Use device managed allocations If setting up smart PC fails for any reason then this can lead to a double free when unloading amd-pmf. This is because dev->buf was freed but never set to NULL and is again freed in amd_pmf_remove(). To avoid subtle allocation bugs in failures leading to a double free change all allocations into device managed allocations.
