1) Buffer overflow

EUVDB-ID: #VU64137

Risk: Low

CVSSv3.1: 5.7 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-30552

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error in the implementation of IP Packet Defragmentation. A remote attacker on the local network can trigger memory corruption and cause a denial of service condition on the target system.

Mitigation

Update the affected package u-boot to the latest version.

2) Out-of-bounds write

EUVDB-ID: #VU64139

Risk: Medium

CVSSv3.1: 8.3 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-30790

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input in the implementation ofIP Packet Defragmentation. A remote attacker on the local netwotk can trigger out-of-bounds write and execute arbitrary code on the target system.

Mitigation

Update the affected package u-boot to the latest version.

3) Stack-based buffer overflow

EUVDB-ID: #VU66594

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-2022-34835

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: No

Description

The vulnerability allows an attacker to escalate privileges on the system.

The vulnerability exists due to a boundary error in the do_i2c_md() function within the "i2c md" command. An attacker with physical access to device can trigger a stack-based buffer overflow and escalate privileges on the system.

Mitigation

Update the affected package u-boot to the latest version.
