Selective Acknowledgement (SACK) in FreeBSD 5.3 and 5.4 does not properly handle an incoming selective acknowledgement when there is insufficient memory, which might allow remote attackers to cause a denial of service (infinite loop).

Does this matter?

Lower severity and a low EPSS score (2.88%). Track it; it rarely justifies an emergency change on its own.
