Red Hat Bugzilla – Bug 169262
CVE-2005-3055 async usb devio oops
Last modified: 2007-11-30 17:06:54 EST
Although the issue below is for linux-2.6 the code in linux-2.4 looks pretty
much identical so this issue may affect RHEL2.1
+++ This bug was initially created as a clone of Bug #169260 +++
Harald Welte mailed the lkml on 20050925 with a report of how to cause a local
oops if a user has permissions to access an arbitrary usb device. I've rated
this as 'moderate' instead of 'important' due to that requirement. Although usb
permissions will be given automatically to console users, a DOS from a user who
has physical access to a machine is little extra risk and we ignore that from
the severity calculation.

Harald Welte's final patch for 2.6, adapted to rhel2.1
fix is in as well as upstream, no test case that I can find exists, but the
problem and fix are well understood at this point.
