CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
When processing the header of an incoming message, libnv failed to properly validate the message size.
The lack of validation allows a malicious program to write outside the bounds of a heap allocation. This can trigger a crash or system panic, and it may be possible for an unprivileged user to exploit the bug to elevate their privileges.
