Security Bulletin
This security bulletin contains one high risk vulnerability.
1) Use-after-free
EUVDB-ID: #VU72308
Risk: High
CVSSv4.0: 5.9 [CVSS:4.0/AV:L/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-2022-1050
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a malicious guest to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the QEMU implementation of VMWare's paravirtual RDMA device. A specially crafted driver on a malicious guest can execute HW commands when shared buffers are not yet allocated, trigger a use-after-free error and execute arbitrary code on the QEMU host.
Install updates from vendor's repository.
