CVE-2023-4039

CVE-2023-4039 describes a GCC stack-protector issue on AArch64: failure of -fstack-protector to detect buffer overflows in C99-style dynamically-sized locals/alloca, unlike static locals. The default overflow handling would terminate the process, but an attacker might influence control flow if an...
