there is a local root exploit by integer underflow in the bluetooth handling,
triggerable by any user if you have bluetooth modules installed.

(I think using socket(AF_BLUETOOTH, -index, x); )

Marcel has posted below patch, I am not sure which bk tree that is it is
however.

CAN-2005-0750 as by Mark J Cox.

An actual exploit supposedly exist already.

This also affects the 2.4 series.

From solar :
grsec-sources-2.4.30 is in the tree as ~arch.

Note for other bumpers of 2.4.x series.
CAN-2004-1056.patch and linux-2.4.28-random-poolsize.patch have never 
been applied to mainline.
