Description

AI Translation Available

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.
