NewCVE-2026-88840 (opens in a new tab)How to fix?
There is no fixed version for busybox.
Overview
Affected versions of this package are vulnerable to Out-of-bounds Read in the get_client_hello process. An attacker can access sensitive information by sending a specially crafted, truncated ClientHello message that causes the process to read past the end of the input buffer. This is only exploitable if the ssl_server applet is compiled and used, as it is not included by default in certain distributions.
Workaround
This vulnerability can be mitigated by avoiding the use of the ssl_server applet in production deployments.
