Dan Rosenberg c25a785d66 score: fix off-by-one index into syscall table ... If the provided system call number is equal to __NR_syscalls, the current check will pass and a function pointer just after the system call table may be called, since sys_call_table is an array with total size __NR_syscalls. Whether or not this is a security bug depends on what the compiler puts immediately after the system call table. It's likely that this won't do anything bad because there is an additional NULL check on the syscall entry, but if there happens to be a non-NULL value immediately after the system call table, this may result in local privilege escalation.
