CVE-2023-42752 – Kernel: integer overflow in igmpv3_newpack leading to exploitable memory access
https://notcve.org/view.php?id=CVE-2023-42752
13 Oct 2023 — 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. Se encontró una falla de desbordamiento de enteros en el kernel de Linux.
