1) If bug results in browser/plugin sigsegv/freeze (resolvable with killing frozen process) or artefacts inside browser window, then, yes, ball on adobe side.
2) If (improper|buggy) use of vdpau/glx results in system/xorg freeze and not resolvable with killing browser/plugin process, then this is still nvidia driver bug, and MUST be fixed inside nvidia driver (very likely in kernel part of driver). No matter if Flash plugin buggy too or not (moreover, if some knownly buggy plugin version triggers such effects, it should be used for testing, even if there are fixed version).
No (unprivileged) user application should be able to freeze system/xorg/make unkillable processes (stuck in "state D")/etc. Otherwise this is EXPLOITABLE SECURITY PROBLEM.
Reports from artem and Lamieur matches (2), and this looks much more serious, than "just" flash problem.
