NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64k-debug-modules package and not the kernel-64k-debug-modules package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

netfilter: complete validation of user input

In my recent commit, I missed that do_replace() handlers use copy_from_sockptr() (which I fixed), followed by unsafe copy_from_sockptr_offset() calls.

In all functions, we can perform the @optlen validation before even calling xt_alloc_table_info() with the following check:

if ((u64)optlen < (u64)tmp.size + sizeof(tmp)) return -EINVAL;
