CVE-ID: CVE-2022-30552
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe 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.
MitigationUpdate the affected package u-boot to the latest version.
Vulnerable software versionsSUSE Linux Enterprise Server: 12-SP4-LTSS
u-boot-tools-debuginfo: before 2018.03-4.6.1
u-boot-tools: before 2018.03-4.6.1
