2) Use-after-free
EUVDB-ID: #VU58813
Risk: High
CVSSv4.0: 6.1 [CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2021-3748
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a remote guest to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when in the virtio-net device of QEMU. A malicious guest can trigger the use-after-free error and execute arbitrary code on the host system with QEMU privileges.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
MitigationUpdate the affected package qemu to the latest version.
