CVE-2018-1108
kernel drivers before version 4.17-rc1 are vulnerable to a weakness in the Linux kernel's implementation of random seed data.
Does this matter?
Lower severity and a low EPSS score (1.73%). Track it; it rarely justifies an emergency change on its own.
Description
kernel drivers before version 4.17-rc1 are vulnerable to a weakness in the Linux kernel's implementation of random seed data. Programs, early in the boot sequence, could use the data allocated for the seed before it was sufficiently generated.
