Technical details
The vulnerability is an input validation flaw in NSC veneer functions that fail to properly validate pointers and data supplied by non-secure callers. This can be exploited to trigger timing side-channels, TOCTOU conditions, format-string misuse, or out-of-bounds memory access. An attacker with non-secure-world code execution can leverage this to read secure-world memory or cause denial of service.
