Candidate: CVE-2009-3238
Description:
The get_random_int function in drivers/char/random.c in the Linux kernel before
2.6.30 produces insufficiently random numbers, which allows attackers to predict the
return value, and possibly defeat protection mechanisms based on randomization, via
vectors that leverage the function's tendency to "return the same value over and
over again for long stretches of time."
