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-2022-27664
DESCRIPTION: Golang Go is vulnerable to a denial of service, caused by a flaw in net/http. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to cause a closing HTTP/2 server connection to hang, and results in a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/235355 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2022-30633
DESCRIPTION: Golang Go is vulnerable to a denial of service, caused by an uncontrolled recursion flaw in Unmarshal in encoding/xml due to stack exhaustion. By parsing a specially-crafted XML document, a remote attacker could exploit this vulnerability to cause a panic.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/233146 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2021-33194
DESCRIPTION: Golang Go is vulnerable to a denial of service, caused by an infinite loop in golang.org/x/net/html. By sending a specially-crafted ParseFragment input, a remote attacker could exploit this vulnerability to cause a denial of service condition.

CVEID: CVE-2022-32206
DESCRIPTION: cURL libcurl is vulnerable to a denial of service, caused by a flaw in the number of acceptable "links" in the "chained" HTTP compression algorithms. By persuading a victim to connect a specially-crafted server, a remote attacker could exploit this vulnerability to insert a virtually unlimited number of compression steps, and results in a denial of service condition.
CVSS Base score: 4.3

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L)
CVEID: CVE-2022-32208
DESCRIPTION: cURL libcurl is vulnerable to a man-in-the-middle attack, caused by a flaw in the handling of message verification failures. An attacker could exploit this vulnerability to launch a man-in-the-middle attack and gain access to the communication channel between endpoints to inject data to the client..
CVSS Base score: 3.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/229742 for the current score.
CVSS Vector: (CVSS:3.0/AV:A/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N)
CVEID: CVE-2022-1729
DESCRIPTION: Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by a race condition in the perf subsystem. By sending specially-crafted syscalls, an authenticated attacker could exploit this vulnerability to gain elevated privileges to root.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/227038 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2022-32250
DESCRIPTION: Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by a use-after-free write flaw in the netfilter subsystem. By executing a specially-crafted program, an authenticated attacker could exploit this vulnerability to gain elevated privileges.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/228676 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2022-27666
DESCRIPTION: Linux Kernel is vulnerable to a buffer overflow, caused by improper bounds checking by the ESP transformation in net/ipv4/esp4.c and net/ipv6/esp6.c. By sending a large message, a local attacker could overflow a buffer and execute arbitrary code on the system or gain elevated privileges in some configurations.
CVSS Base score: 8.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/222414 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2022-35252
DESCRIPTION: cURL libcurl is vulnerable to a denial of service, caused by a flaw when cookies contain control codes are later sent back to an HTTP(S) server. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to cause a "sister site" to deny service to siblings.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/234980 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2020-28915
DESCRIPTION: Linux Kernel could allow a local attacker to obtain sensitive information, caused by a buffer over-read flaw in the fbcon code. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain kernel memory 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/191993 for the current score.

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
