CVE-2025-38258

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mm/damon/sysfs-schemes: free old damon_sysfs_scheme_filter-&gt;memcg_path on write<br /> <br /> memcg_path_store() assigns a newly allocated memory buffer to<br /> filter-&gt;memcg_path, without deallocating the previously allocated and<br /> assigned memory buffer. As a result, users can leak kernel memory by<br /> continuously writing a data to memcg_path DAMOS sysfs file. Fix the leak<br /> by deallocating the previously set memory buffer.
