There are multiple vulnerabilities in Linux Kernel Version used by IBM QRadar SIEM. IBM QRadar SIEM has addressed the applicable CVEs.
CVEID:CVE-2021-22543
**DESCRIPTION:**Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by improper handling of VM_IO|VM_PFNMAP vmas in KVM. By sending a specially-crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges to start and control a VM to read/write random pages of memory.
CVSS Base score: 7.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/202561 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N)
CVEID:CVE-2021-3653
**DESCRIPTION:**Linux Kernel is vulnerable to a denial of service, caused by improper input validation of the “int_ctl” VMCB field. By sending a specially-crafted request, a local authenticated attacker could exploit this vulnerability to cause the system to crash or obtain sensitive information from the physical memory.
CVSS Base score: 7.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/207522 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H)
CVEID:CVE-2021-3656
**DESCRIPTION:**Linux Kernel is vulnerable to a denial of service, caused by improper input validation of the “virt_ext” VMCB field. By sending a specially-crafted request, a local authenticated attacker could exploit this vulnerability to cause the system to crash or obtain sensitive information from the physical memory.
CVSS Base score: 7.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/207523 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H)
CVEID:CVE-2021-37576
**DESCRIPTION:**Linux Kernel for PowerPC could allow a local authenticated attacker to execute arbitrary code on the system, caused by a memory corruption flaw in the handling of the H_RTAS hypercall. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/206372 for the current score.
