CVSS 8.8 · High EPSS 0,65%

Kerentanan Out-of-bounds Write pada freebsd. Skor CVSS 3.1 8.8 (High) menurut CISA ADP.

Deskripsi (NVD)

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.
