CVE-2025-38258

Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)

Description: A memory leak exists in the Linux kernel due to improper memory management within the memcg path store() function. Specifically, the function allocates a new memory buffer for filter->memcg path without deallocating the previously allocated buffer. This allows users to leak kernel memory by repeatedly writing data to the memcg path DAMOS sysfs file.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
