CVE-2019-19396
illumos, as used in OmniOS Community Edition before r151030y, allows a kernel crash via an application with multiple threads calling sendmsg concurrently over a single socket, because uts/common/inet/ip/ip_attr.c mishandles conn_ixa dereferences.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.12%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
