"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nNFS: Fix use-after-free in nfs4_init_client()\n\nKASAN reports a use-after-free when attempting to mount two different\nexports through two different NICs that belong to the same server.\n\nOlga was able to hit this with kernels starting somewhere between 5.7\nand 5.10, but I traced the patch that introduced the clear_bit() call to\n4.13. So something must have changed in the refcounting of the clp\npointer to make this call to nfs_put_client() the very last one."

"value": " En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: scsi: core: corrige el manejo de errores de scsi_host_alloc(). Despu\u00e9s de que el dispositivo se inicializa mediante device_initialize(), o su nombre se establece mediante dev_set_name(), el dispositivo debe liberarse mediante put_device (). De lo contrario, se filtrar\u00e1 el nombre del dispositivo porque se asigna din\u00e1micamente en dev_set_name(). Solucione la fuga reemplazando kfree() con put_device(). Dado que scsi_host_dev_release() maneja adecuadamente la eliminaci\u00f3n de IDA y kthread, elimine tambi\u00e9n estas may\u00fasculas y min\u00fasculas especiales del manejo de errores."
