Detailsinfo

A vulnerability was found in Linux Kernel up to 6.17.5. It has been declared as critical. This vulnerability affects the function damon_destroy_scheme. The manipulation with an unknown input leads to a memory leak vulnerability. The CWE definition for the vulnerability is CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. As an impact it is known to affect availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: mm/damon/core: fix potential memory leak by cleaning ops_filter in damon_destroy_scheme Currently, damon_destroy_scheme() only cleans up the filter list but leaves ops_filter untouched, which could lead to memory leaks when a scheme is destroyed. This patch ensures both filter and ops_filter are properly freed in damon_destroy_scheme(), preventing potential memory leaks.

The advisory is available at git.kernel.org. This vulnerability was named CVE-2025-40229 since 04/16/2025. Technical details are known, but there is no available exploit.
