        "Description": "This update upgrades kernel-image-std-def to version 5.10.43-alt1. \nSecurity Fix(es):\n\n * BDU:2021-04862: Уязвимость функции hci_dev_do_open() подсистемы инициализации устройства HCI ядра операционной системы Linux, связанная с повторным освобождением памяти, позволяющая нарушителю вызвать отказ в обслуживании\n\n * CVE-2021-28691: Guest triggered use-after-free in Linux xen-netback A malicious or buggy network PV frontend can force Linux netback to disable the interface and terminate the receive kernel thread associated with queue 0 in response to the frontend sending a malformed packet. Such kernel thread termination will lead to a use-after-free in Linux netback when the backend is destroyed, as the kernel thread associated with queue 0 will have already exited and thus the call to kthread_stop will be performed against a stale pointer.\n\n * CVE-2021-3564: A flaw double-free memory corruption in the Linux kernel HCI device initialization subsystem was found in the way user attach malicious HCI TTY Bluetooth device. A local user could use this flaw to crash the system. This flaw affects all the Linux kernel versions starting from 3.13.",
