Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.10.6

Description The issue is related to the netfilter component of the Linux kernel, specifically the nfnetlink component. The problem arises from the missing initialization of the extack buffer when acknowledging BATCH BEGIN and BATCH END. This could potentially allow an attacker to impact the confidentiality, integrity, and availability of protected information. The vulnerability is related to the nfnetlink rcv batch() function in the net/netfilter/nfnetlink.c module.

Recommendations For Linux kernel versions prior to 6.10.6, upgrade to version 6.10.6 or later to mitigate the risk. As a temporary workaround, consider restricting access to the vulnerable nfnetlink component until a patch is applied. Avoid using the nfnetlink component for critical operations until the issue is resolved.
