CVE-2019-9003
In the Linux kernel before 4.20.5, attackers can trigger a drivers/char/ipmi/ipmi_msghandler.c use-after-free and OOPS by arranging for certain simultaneous execution of the code, as demonstrated by a "service ipmievd restart" loop.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.75%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
