There are security vulnerabilities in versions of Linux Kernel that are shipped with versions of IBM Elastic Storage System. A fix for these vulnerabilities is available.
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
