CVE-2022-49727
Last modified
CVE-2022-49727 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: ipv6: Fix signed integer overflow in l2tp_ip6_sendmsg When len >= INT_MAX - transhdrlen, ulen = len + transhdrlen will be overflow. To fix, we can follow what udpv6 does and subtract the transhdrlen from the max.. EPSS estimates a 0.27% chance of exploitation in the next 30 days.
