CVE-2021-47010
CVE-2021-47010 is a Linux kernel issue affecting the global tcp congestion control default when set from the init netns. The root cause is that tcp_set_default_congestion_control() writes to net.ipv4.tcp_congestion_control in a non-namespaced way and toggles TCP_CONG_NON_RESTRICTED, changing the ...
