1) NULL pointer dereference

EUVDB-ID: #VU73782

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-2022-3606

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 within the find_prog_by_sec_insn() function in tools/lib/bpf/libbpf.c of the BPF component. A local user can perform a denial of service (DoS) attack.

Mitigation

2) 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.
