kernel is vulnerable to privilege escalation. A use-after-free in the tcpmss_mangle_packet
function in net/netfilter/xt_TCPMSS.c
allows remote attackers to cause a denial of service by leveraging the presence of xt_TCPMSS
in an iptables
action. The successful exploit of the vulnerable can potentially lead to privilege escalation as well.
