CVE-2024-42269: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: netfilter: iptables: Fix potential null-ptr-deref in ip6table_nat_table_init(). ip6table_nat_table_init() accesses net->gen->ptr[ip6table_nat_net_ops.id], but the function is exposed to user space before the entry is allocated via register_pernet_subsys(). Let's call register_pernet_subsys() before xt_register_template().

Affected products

• Linux Linux Kernel: from 5.15, before 6.1.104 (fixed in 6.1.104); from 6.2, before 6.6.45 (fixed in 6.6.45); from 6.7, before 6.10.4 (fixed in 6.10.4); version 6.11 only
