kernel: denial of service via ioctl call in network tun handling (CVE-2018-7191)
kernel: usb: missing size check in the __usb_get_extra_descriptor() leading to DoS (CVE-2018-20169)
kernel: perf_event_open() and execve() race in setuid programs allows a data leak (CVE-2019-3901)
kernel: use-after-free in arch/x86/lib/insn-eval.c (CVE-2019-13233)
kernel: memory leak in register_queue_kobjects() in net/core/net-sysfs.c leads to denial of service (CVE-2019-15916)
kernel: powerpc: incomplete Spectre-RSB mitigation leads to information exposure (CVE-2019-18660)
