CVE-2024-26845
Estado: ModificadaMedia (5.5)—
Detalles técnicos trazas, registros y código del informe original
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: scsi: target: core: agregar TMF al manejo de tmr_list. Una cancelación a la que responde iSCSI se agrega a tmr_list pero no va al núcleo de destino. Un LUN_RESET que pasa por tmr_list toma un refcounter al cancelar y espera a que se complete. Sin embargo, la cancelación nunca se completará porque no se inició en el núcleo de destino. No se puede ubicar ITT: 0x05000000 en CID: 0 No se puede ubicar RefTaskTag: 0x05000000 en CID: 0. wait_for_tasks: Deteniendo tmf LUN_RESET con etiqueta 0x0 ref_task_tag 0x0 i_state 34 t_state ISTATE_PROCESSING refcnt 2 transport_state active,stop,fabric_stop esperar tareas: t mf LUN_RESET con etiqueta 0x0 ref_task_tag 0x0 i_state 34 t_state ISTATE_PROCESSING refcnt 2 transport_state active,stop,fabric_stop ...
