Security Bulletin

This security bulletin contains information about 13 vulnerabilities.

1) Information exposure through microarchitectural state after transient execution

EUVDB-ID: #VU79262

Risk: Medium

CVSSv3.1: 7.6 [CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-40982

CWE-ID: CWE-1342 - Information Exposure through Microarchitectural State after Transient Execution

Exploit availability: No

Description

The vulnerability allows a malicious guest to escalate privileges on the system.

The vulnerability exists due to the way data is shared between threads whereby the AVX GATHER instructions on Intel processors can forward the content of stale vector registers to dependent instructions. A malicious guest can infer data from different contexts on the same core and execute arbitrary code with elevated privileges.

Mitigation

Update the affected package the Linux Kernel to the latest version.

3) Information disclosure

EUVDB-ID: #VU79263

Risk: Low

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-20569

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows a remote user to gain access to potentially sensitive information.

The vulnerability exists due to a side channel issue in AMD CPUs. A remote user can influence the return address prediction and gain unauthorized access to sensitive information on the system.

Mitigation

Update the affected package the Linux Kernel to the latest version.

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-20593

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error in AMD Zen2 processors. A local user can trigger a use-after-free error and execute arbitrary code on the system.

Note, the vulnerability was dubbed Zenbleed.

Mitigation

Update the affected package the Linux Kernel to the latest version.

CVSSv3.1: 6.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-34319

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a malicious guest to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in netback when processing certain packets. A malicious guest can send specially crafted packets to the backend, trigger memory corruption and crash the hypervisor.

Mitigation

Update the affected package the Linux Kernel to the latest version.

8) Use-after-free

EUVDB-ID: #VU79491

Risk: Low

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-3567

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error within the vc_screen() function in vcs_read in drivers/tty/vt/vc_screen.c. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.

Mitigation

Update the affected package the Linux Kernel to the latest version.

12) Use-after-free

EUVDB-ID: #VU79927

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-4133

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a use-after-free error within the cxgb4 driver in the Linux kernel. A local user can trigger a use-after-free and crash the kernel.

Mitigation

Update the affected package the Linux Kernel to the latest version.

13) Type Confusion

EUVDB-ID: #VU79485

Risk: Low

CVSSv3.1: 2.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-4194

CWE-ID: CWE-843 - Type confusion

Exploit availability: No

Description

The vulnerability allows a local user to bypass implemented security restrictions.

The vulnerability exists due to a type confusion error in TUN/TAP functionality. A local user can bypass network filters and gain unauthorized access to some resources.

The vulnerability exists due to incomplete fix for #VU72742 (CVE-2023-1076).

Mitigation

Update the affected package the Linux Kernel to the latest version.
