  3. CVE-2026-23142
In the Linux kernel, the following vulnerability has been resolved: mm/damon/sysfs-scheme: cleanup access_pattern subdirs on scheme dir setup failure When a DAMOS-scheme DAMON sysfs directory setup fails after setup of access_pattern/ directory, subdirectories of access_pattern/ 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-scheme: limpieza de los subdirectorios de access_pattern en caso de fallo en la configuración del directorio del esquema Cuando la configuración de un directorio sysfs de DAMON con esquema DAMOS falla después de la configuración del directorio access_pattern/, los subdirectorios del directorio access_pattern/ no se limpian. Como resultado, la interfaz sysfs de DAMON queda casi rota hasta que el sistema se reinicia, y la memoria del directorio no eliminado se fuga. Limpiar los directorios en caso de tales fallos.
