Overview

What is CVE-2026-72177?

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

mm/damon/sysfs-schemes: fix dir put orders in access_pattern_add_dirs()

Patch series "mm/damon/sysfs-schemes: fix wrong directories put orders in error paths".

Error paths of damon_sysfs_access_pattern_add_dirs() and damon_sysfs_scheme_add_dirs() functions put references to directories in wrong orders. As a result, uninitialized memory dereference and/or memory leak can happen.

Fix those.

This patch (of 2):

In access_pattern_add_dirs(), error handling path puts references starting from setup failed directories. If the failure happpened from the initial allication in the setup functions, uninitialized memory dereference happen.

The allocation failures will not commonly happen, but the consequence is quite bad. Fix the wrong reference put orders.

The issue was discovered [1] by Sashiko.
