As a result, malicious clients could send short messages which would result in a large memory allocation, potentially leading to denial of service.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.56%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
