https://notcve.org/view.php?id=CVE-2021-47427
In the Linux kernel, the following vulnerability has been resolved: scsi: iscsi: Fix iscsi_task use after free Commit d39df158518c ("scsi: iscsi: Have abort handler get ref to conn") added iscsi_get_conn()/iscsi_put_conn() calls during abort handling but then also changed the handling of the case where we detect an already completed task where we now end up doing a goto to the common put/cleanup code. This results in a iscsi_task use after free, because the common cleanup code will do a put on the iscsi_task. This reverts the goto and moves the iscsi_get_conn() to after we've checked if the iscsi_task is valid. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: scsi: iscsi: corrige el uso after free de iscsi_task. Confirmación d39df158518c ("scsi: iscsi: Have abort handler get ref to conn") se agregaron llamadas iscsi_get_conn()/iscsi_put_conn() durante el manejo de abortos pero luego también cambió el manejo del caso en el que detectamos una tarea ya completada y ahora terminamos haciendo un acceso al código común de put/cleanup. Esto da como resultado un uso de iscsi_task después de la liberación, porque el código de limpieza común colocará iscsi_task. • https://git.kernel.org/stable/c/d39df158518ccc3bf24ee18082b5e100c8f014aa https://git.kernel.org/stable/c/1642f51ac0d4f2b55d5748094c49ff8f7191b93c https://git.kernel.org/stable/c/258aad75c62146453d03028a44f2f1590d58e1f6 •

In the Linux kernel, the following vulnerability has been resolved: i2c: acpi: fix resource leak in reconfiguration device addition acpi_i2c_find_adapter_by_handle() calls bus_find_device() which takes a reference on the adapter which is never released which will result in a reference count leak and render the adapter unremovable. Make sure to put the adapter after creating the client in the same manner that we do for OF. [wsa: fixed title] En el kernel de Linux, se resolvió la siguiente vulnerabilidad: i2c: acpi: corrige la fuga de recursos en la reconfiguración del dispositivo añdido acpi_i2c_find_adapter_by_handle() llama a bus_find_device() que toma una referencia en el adaptador que nunca se libera, lo que resultará en una fuga de recuento de referencias y haga que el adaptador no sea extraíble. Asegúrese de colocar el adaptador después de crear el cliente de la misma manera que lo hacemos para OF.
