Description Marcel Holtmann 2007-09-05 08:43:15 UTC

From Victor Julien:

There exists a way to crash the Linux kernel by sending a single IPv6 packet at it.

Comment 4 Marcel Holtmann 2007-09-05 08:52:11 UTC

Created attachment 187121 [details]
Linus thinks this patch fixed it upstream (not verified)

Comment 6 Thomas Graf 2007-09-05 15:21:47 UTC

Note, no RHEL tree is affected to this. This bug has been introduced with the
patch [IPV6]: Per-interface statistics support. which was accepted in 2.6.20
therefore the vulnerable code was never included in any of our releases.
