CVE-2008-0009
The vmsplice_to_user function in fs/splice.c in the Linux kernel 2.6.22 through 2.6.24 does not validate a certain userspace pointer before dereference, which might allow local users to access arbitrary kernel memory locations.
LOW 2.1EPSS 0.96%
Does this matter?
Lower severity and a low EPSS score (0.96%). Track it; it rarely justifies an emergency change on its own.
