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.
:heavy_check_mark: This issue was automatically closed by Mend because the vulnerable library in the specific branch(es) was either marked as ignored or it is no longer part of the Mend inventory.
