Does this matter?
Lower severity and a low EPSS score (1.73%). Track it; it rarely justifies an emergency change on its own.
Description
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.
