Summary

Multiple vulnerabilities in the Linux kernel could allow a remote attacker to obtain sensitive information from IBM SAN Volume Controller, IBM Storwize, IBM Spectrum Virtualize and IBM FlashSystem products.

Vulnerability Details

CVEID:CVE-2022-1012
**DESCRIPTION:**Linux Kernel could allow a remote attacker to obtain sensitive information, caused by a memory leak flaw in the TCP source port generation algorithm in the net/ipv4/tcp.c function. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain sensitive information or cause a denial of service condition.
CVSS Base score: 8.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/230055 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H)

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.
CVSS Base score: 6.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/216134 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)
