Luxion KeyShot versions prior to 10.1, Luxion KeyShot Viewer versions prior to 10.1, Luxion KeyShot Network Rendering versions prior to 10.1, and Luxion KeyVR versions prior to 10.1 are vulnerable to an out-of-bounds read while processing project files,…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.15%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
