CVE-2023-39945
Prior to versions 2.11.0, 2.10.2, 2.9.2, and 2.6.5, a data submessage sent to PDP port raises unhandled `BadParamException` in fastcdr, which in turn crashes fastdds.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.94%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
