CVE-2020-10699
If a system enables the targetclid socket, a local attacker can use this flaw to modify the iSCSI configuration and escalate their privileges to root.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.34%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
