Description

CVE-2025-38258 affecting package kernel for versions less than 6.6.96.1-1

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

mm/damon/sysfs-schemes: free old damon_sysfs_scheme_filter->memcg_path on write

memcg_path_store() assigns a newly allocated memory buffer to

filter->memcg_path, without deallocating the previously allocated and

assigned memory buffer. As a result, users can leak kernel memory by

continuously writing a data to memcg_path DAMOS sysfs file. Fix the leak

by deallocating the previously set memory buffer.
