Vulnerability from github – Published: 2024-02-15 06:31 – Updated: 2024-08-29 21:31

Details

The bug can be triggered by a malicious bhyve guest kernel to overwrite memory in the bhyve(8) process. This could potentially lead to user-mode code execution on the host, subject to bhyve's Capsicum sandbox.

Severity ?

8.8 (High)

CVE-2022-23092 (GCVE-0-2022-23092)

Vulnerability from cvelistv5 – Published: 2024-02-15 05:13 – Updated: 2025-02-13 16:29

Summary

The implementation of lib9p's handling of RWALK messages was missing a bounds check needed when unpacking the message contents. The missing check means that the receipt of a specially crafted message will cause lib9p to overwrite unrelated memory. The bug can be triggered by a malicious bhyve guest kernel to overwrite memory in the bhyve(8) process. This could potentially lead to user-mode code execution on the host, subject to bhyve's Capsicum sandbox.

Severity ?

8.8 (High)
