Open5GS before 2.7.1 is vulnerable to a reachable assertion that can cause an AMF crash via NAS messages from a UE: ogs_nas_encrypt in lib/nas/common/security.c for pkbuf->len.
The product uses a sequential operation to read or write a buffer, but it uses an incorrect length value that causes it to access memory that is outside of the bounds of the buffer.
https://cwe.mitre.org/data/definitions/805.html →Open in CWE collection →Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an adversary. As a consequence, an adversary is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the adversaries' choice.

If the server processing the transmission naively trusts the specified size, then an attacker can intentionally understate the size of the array, possibly resulting in a buffer overflow if the server attempts to read the entire data set into the memory it allocated for a smaller array.
