Security Bulletin
This security bulletin contains one medium risk vulnerability.
EUVDB-ID: #VU68551
Risk: Medium
CVSSv4.0: 4.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2022-0216
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error in the LSI53C895A SCSI Host Bus Adapter emulation of QEMU when processing repeated messages to cancel the current SCSI request via the lsi_do_msgout() function. A remote user on the guest OS can trigger a use-after-free error and perform a denial of service attack against the QEMU host.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
MitigationInstall updates from vendor's repository.
