Description
The issue is related to the netfilter component of the Linux kernel, specifically with the nft ct module. It involves insufficient validation of user-input data in the
nft ct expect obj init() function, which can lead to a denial of service. The vulnerability is addressed by sanitizing layer 3 and 4 protocol numbers in custom expectations, disallowing families other than NFPROTO {IPV4,IPV6,INET}, and disallowing layer 4 protocols with no ports.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
