1 | Hi everyone, |
2 | |
3 | I noticed a new option in configuring PaX in the kernel with version |
4 | 2.6.26. It says: |
5 | |
6 | Prevent various kernel object reference counter overflows |
7 | |
8 | The description says that it "prevents overflowing various (but not all) |
9 | kinds of object reference counters." I'm not familiar with this exploit |
10 | technique. Does anyone know of any proof of concept code? |
