Doc Text:	A flaw was found in the Linux kernel in the function soc_tplg_dapm_graph_elems_load() which could lead to a use-after-free vulnerability as there are direct references in memory to topology file elements which could have been freed after parsing. This vulnerability could lead to memory corruption or crashes.	Story Points:	---

Description OSIDB Bzimport 2024-07-29 15:44:48 UTC

In the Linux kernel, the following vulnerability has been resolved:

ASoC: topology: Fix references to freed memory

Most users after parsing a topology file, release memory used by it, so
having pointer references directly into topology file contents is wrong.
Use devm_kmemdup(), to allocate memory as needed.
