Title:
bluetooth disconnection corrupts memory and causes kernel panic
Status in “linux” package in Ubuntu:
Fix Released
Status in “linux” source package in Raring:
In Progress
Status in “linux” source package in Saucy:
Fix Released
Bug description:
This bug is present on kernels v3.8-rc1 and beyond and was exposed by commit
ecbbfd44.
To reproduce:
1) Pair a bluetooth device that is capable of being easily powered down (a
phone for example)
2) Configure /etc/bluetooth/rfcomm.conf to connect to device. For example:
rfcomm0 {
bind no;
device XX:XX:XX:XX:XX:XX;
channel XX;
comment "phone";
}
3) Type 'rfcomm connect 0'.
4) On the device power down the bluetooth component or power down the device.
5) Eventually the machine will crash, I've found that exec'ing another
program will cause the crash easily.
