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?
