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.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/202644 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-2022-32206
**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 Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/229740 for the current score.
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 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.

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.
