Last modified

CVE-2007-4311 is a vulnerability of currently unknown severity. The xfer_secondary_pool function in drivers/char/random.c in the Linux kernel 2.4 before 2.4.35 performs reseed operations on only the first few bytes of a buffer, which might make it easier for attackers to predict the output of the random number generator, related to incorrect use of the sizeof operator.. EPSS estimates a 1.73% chance of exploitation in the next 30 days.
