Vendor comments

  • Red HatThe Linux kernel as shipped with Red Hat Enterprise Linux 3, 5, and Red Hat Enterprise MRG did not include support for the HiSax ISDN driver for Colognechip HFC-S USB chip, and therefore were not affected by this issue. Issue was addressed in Red Hat Enterprise Linux 4 via https://rhn.redhat.com/errata/RHSA-2010-0076.html
