CVE-2024-42269 Open this link in a new tabHow to fix?
There is no fixed version for RHEL:7 kernel-bootwrapper.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-bootwrapper package and not the kernel-bootwrapper package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
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().
