CVE-2022-22351
IBM AIX 7.1, 7.2, 7.3, and VIOS 3.1 could allow a non-privileged trusted host user to exploit a vulnerability in the nimsh daemon to cause a denial of service in the nimsh daemon on another trusted host.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.19%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
