Vulnerability description
DayBreach CVE AI Research
CVE-2021-45485 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based attackers can typically choose among many IPv6 source addresses.
