Security Bulletin

This security bulletin contains information about 20 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.

EUVDB-ID: #VU78007

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-2023-3390

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 net/netfilter/nf_tables_api.c in the Linux kernel netfilter subsystem. A local user can trigger a use-after-fee error and escalate privileges on the system.

Mitigation

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

19) Out-of-bounds write

EUVDB-ID: #VU78928

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-2023-3812

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error within the TUN/TAP device driver in Linux kernel. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.

Mitigation

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

20) Use-after-free

EUVDB-ID: #VU79498

Risk: Low

CVSSv3.1: 7.7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-4004

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 the way a user triggers the nft_pipapo_remove function with the element, without a NFT_SET_EXT_KEY_END. A local user can execute arbitrary code with elevated privileges.

Mitigation

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