An attacker could exploit this vulnerability to gain elevated privileges on the system. CVSS Base score: 7.5 CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/ 196564 for the current score. CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H) CVEID: CVE-2020-12363 DESCRIPTION: Intel Graphics Drivers are vulnerable to a denial of service, caused by improper input validation. A local authenticated attacker could exploit this vulnerability to cause a denial of service. CVSS Base score: 1.9 CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/ 196581 for the current score. CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:L) CVEID: CVE-2020-12364 DESCRIPTION: Intel Graphics Drivers are vulnerable to a denial of service, caused by a NULL pointer reference error. A local authenticated attacker could exploit this vulnerability to cause a denial of service.

CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:L) CVEID: CVE-2020-27170 DESCRIPTION: Linux Kernel could allow a local authenticated attacker to obtain sensitive information, caused by an out-of-bounds loads flaw. By executing specially-crafted BPF programs, an attacker could exploit this vulnerability to obtain contents of kernel memory, and use this information to launch further attacks against the affected system. CVSS Base score: 5.5 CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/ 198453 for the current score. CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N) CVEID: CVE-2020-8648 DESCRIPTION: Linux kernel could allow a remote attacker to obtain sensitive information, caused by a use-after-free in the n_tty_receive_buf_common function of drivers/tty/n_tty.c. An attacker could exploit this vulnerability to read memory that should not be available for access. CVSS Base score: 5.3 CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/ 175843 for the current score. CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) CVEID: CVE-2021-3347 DESCRIPTION: Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by a kernel stack use-after-free during fault handling in PI futexes. An attacker could exploit this vulnerability to gain elevated privileges and execute arbitrary code in the kernel.
