Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
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.
