Summary

IBM has addressed the CVEs

Vulnerability Details

CVEID:CVE-2021-45485
**DESCRIPTION:**Linux Kernel could allow a local attacker to obtain sensitive information, caused by improperly consider attacks from many IPv6 source addresses in net/ipv6/output_core.c in the IPv6 implementation. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
CVSS Base score: 6.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/216133 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)

CVEID:CVE-2021-45486
**DESCRIPTION:**Linux Kernel could allow a local attacker to obtain sensitive information, caused by the use of small hash table in net/ipv4/route.c in the IPv4 implementation. By utilize cryptographic attack techniques, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
