  3. CVE-2026-23144
In the Linux kernel, the following vulnerability has been resolved: mm/damon/sysfs: cleanup attrs subdirs on context dir setup failure When a context DAMON sysfs directory setup is failed after setup of attrs/ directory, subdirectories of attrs/ directory are not cleaned up. As a result, DAMON sysfs interface is nearly broken until the system reboots, and the memory for the unremoved directory is leaked. Cleanup the directories under such failures.

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: mm/damon/sysfs: limpieza de subdirectorios de attrs en caso de fallo en la configuración del directorio de contexto Cuando la configuración de un directorio sysfs de DAMON de contexto falla después de la configuración del directorio attrs/, los subdirectorios del directorio attrs/ no se limpian. Como resultado, la interfaz sysfs de DAMON queda casi rota hasta que el sistema se reinicia, y la memoria para el directorio no eliminado se fuga. Limpiar los directorios en caso de tales fallos.
