CVE-2021-45485 is an information leak vulnerability in the IPv6 implementation of the Linux kernel, specifically affecting versions prior to 5.13.3, as well as products from NetApp and Oracle utilizing these kernels. Attackers can exploit a weakness in the IPv6 hash table by manipulating source addresses to extract sensitive information. This vulnerability is rated as High severity (CVSS 7.5), requiring no user interaction or privileges, and can be exploited over the network. While the vulnerability is significant, there is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or notable community discussion or media coverage.

CVE-2021-45485
Jan 11, 2022In 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.
