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

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

mm/damon/sysfs-schemes: free old damonsysfsschemefilter->memcgpath on write

memcgpathstore() assigns a newly allocated memory buffer to filter->memcgpath, without deallocating the previously allocated and assigned memory buffer. As a result, users can leak kernel memory by continuously writing a data to memcgpath DAMOS sysfs file. Fix the leak by deallocating the previously set memory buffer.
