Summary
[slab-out-of-bounds in kernel xfrm module function xfrm_state_walk]
Details

In addr_match of xfrm.h, there is a possible out-of-bounds read due to a missing bounds check. This could lead to local information disclosure in the kernel with System execution privileges needed. User interaction is not needed for exploitation.
