CVE-2023-42752

Fixed in a distro release EPSS <1%CVSS 5.5

An integer overflow flaw was found in the Linux kernel. This issue leads to the kernel allocating `skb_shared_info` in the userspace, which is exploitable in systems without SMAP protection since `skb_shared_info` contains references to function pointers.
