CVE-2021-38425
eProsima Fast DDS versions prior to 2.4.0 (#2269) are susceptible to exploitation when an attacker sends a specially crafted packet to flood a target device with unwanted traffic, which may result in a denial-of-service condition and information exposure.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.08%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
