Affected: Linux

In the Linux kernel, the following vulnerability has been resolved:

xfrm: add NULL check in xfrm_update_ae_params

Normally, x->replay_esn and x->preplay_esn should be allocated at xfrm_alloc_replay_state_esn(...) in xfrm_state_construct(...), hence the xfrm_update_ae_params(...) is okay to update them. However, the current implementation of xfrm_new_ae(...) allows a malicious user to directly dereference a NULL pointer and crash the kernel like below.
