No. We are not aware of malware exploiting this vulnerability.

2) Use-after-free

EUVDB-ID: #VU72328

Risk: Low

CVSSv3.1: 5.9 [CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-4382

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows an attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error within the gadgetfs Linux driver. An attacker with physical access to the system can trigger a use-after-free by manipulating the external device with gadgetfs and execute arbitrary code.

Mitigation

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

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

3) NULL pointer dereference

EUVDB-ID: #VU71479

Risk: Medium

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-2022-47929

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

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

The vulnerability exists due to a NULL pointer dereference error in the traffic control subsystem in Linux kernel. A local user can pass pass a specially crafted traffic control configuration that is set up with "tc qdisc" and "tc class" commands and perform a denial of service (DoS) attack.

Mitigation

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

4) NULL pointer dereference

EUVDB-ID: #VU71138

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-0122

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error within the nvmet_setup_auth(0 function in drivers/nvme/target/auth.c. A remote attacker can send specially crafted data to the system and perform a denial of service (DoS) attack.

5) Integer overflow

EUVDB-ID: #VU71173

Risk: Low

CVSSv3.1: 7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2023-0179

CWE-ID: CWE-190 - Integer overflow

Exploit availability: Yes

Description

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

The vulnerability exists due to an integer overflow within the nft_payload_copy_vlan() function in Linux kernel Netfilter. A local user can trigger an integer overflow and execute arbitrary code with elevated privileges.

Mitigation

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

6) Use-after-free

EUVDB-ID: #VU71482

Risk: High

CVSSv3.1: 8.4 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:H/RL:O/RC:C]

CVE-ID: CVE-2023-0266

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 snd_ctl_elem_read() function in the Linux kernel sound subsystem. A local user can trigger a use-after-free error and execute arbitrary code on the system.

Note, the vulnerability is being actively exploited in the wild.

Mitigation

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

EUVDB-ID: #VU72098

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-2023-0590

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 qdisc_graft() function in net/sched/sch_api.c. A local user can trigger a use-after-free error and crash the kernel.

Mitigation

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

9) Type Confusion

EUVDB-ID: #VU71477

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-2023-23455

CWE-ID: CWE-843 - Type confusion

Exploit availability: No

Description

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

The vulnerability exists due to a type confusion error within the atm_tc_enqueue() function in net/sched/sch_atm.c in the Linux kernel. A local user can trigger a type confusion error and perform a denial of service (DoS) attack.

Mitigation

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