CVE-2024-49966

In the Linux kernel, the following vulnerability has been resolved: ocfs2: cancel dqi_sync_work before freeing oinfo ocfs2_global_read_info() will initialize and schedule dqi_sync_work at the end, if error occurs after successfully reading global quota, it will trigger the following warning with CONFIG_DEBUG_OBJECTS_* enabled: ODEBUG: free active (active state 0) object: 00000000d8b0ce28 object type: timer_list hint: qsync_work_fn+0x0/0x16c This reports that there is an active delayed work when freeing oinfo in error handling, so cancel dqi_sync_work first. BTW, return status instead of -1 when .read_file_info fails.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ocfs2: cancelar dqi_sync_work antes de liberar oinfo ocfs2_global_read_info() inicializará y programará dqi_sync_work al final, si ocurre un error después de leer exitosamente la cuota global, activará la siguiente advertencia con CONFIG_DEBUG_OBJECTS_* habilitado: ODEBUG: free active (active state 0) object: 00000000d8b0ce28 object type: timer_list hint: qsync_work_fn+0x0/0x16c Esto informa que hay un trabajo retrasado activo al liberar oinfo en el manejo de errores, así que cancele dqi_sync_work primero. POR CIERTO, devuelva el estado en lugar de -1 cuando .read_file_info falle.
