The vulnerability of the xt_replace_table() function in the net/netfilter/x_tables.c module of the Linux kernel’s netfilter firewall allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the xtreplacetable function in the net/netfilter/xtables.c module of the Linux kernel’s netfilter firewall is related to the use of previously freed memory due to competitive access to resources. This occurs due to insufficient synchronization between processes. Exploiting th...
