2) Resource management error
EUVDB-ID: #VU66871
Risk: Medium
CVSSv4.0: 5.6 [CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H/E:U/U:Green]
CVE-ID: CVE-2022-2132
CWE-ID:
CWE-399 - Resource Management Errors
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the copy_desc_to_mbuf() function when processing Vhost header. A remote guest can send a packet with the Vhost header crossing more than two descriptors and force application to allocate all available mbufs, causing a denial of service condition for the other guest running on the hypervisor.
