A race condition was found in the Linux kernel’s IP framework for
transforming packets (XFRM subsystem) when multiple calls to
xfrm_probe_algs occurred simultaneously. This flaw could allow a local
attacker to potentially trigger an out-of-bounds write or leak kernel heap
memory by performing an out-of-bounds read and copying it into a socket.
