Description:
|
| 5 |
Alignment Check (AC) flag in EFLAGS is not saved/restored during task
|
| 6 |
switch, thus was leaking to other tasks. Those eventually died with a
|
| 7 |
SIGBUS.
|
| 8 |
Ubuntu-Description:
|
| 9 |
The task switching code did not save and restore EFLAGS of processes.
|
| 10 |
By starting a specially crafted executable, a local attacker could
|
| 11 |
exploit this to eventually crash many other running processes.
|
| 12 |
Notes:
|
| 13 |
incorrect optimization in some later 2.6.x kernel, reverted
|
| 14 |
Local DoS.
|
| 15 |
|
| 16 |
Are we sure this affects 2.6.17 and before? The CFI_ADJUST_CFA_OFFSET
|
| 17 |
doesn't seem to be present in these kernels.
