Severity CVSS v4.0:
Pending analysis
Type:
CWE-415 Double Free
Publication date:

Description

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