This security bulletin contains information about 2 vulnerabilities.

1) Stack-based buffer overflow

EUVDB-ID: #VU87165

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2024-1151

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

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 Open vSwitch sub-component in the Linux Kernel. A remote unauthenticated attacker can send specially crafted packets to the system. trigger a stack-based buffer overflow and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.
