kernel: eBPF multiplication integer overflow in prealloc_elems_and_freelist() in kernel/bpf/stackmap.c leads to out-of-bounds write

An out-of-bounds OOB memory write flaw was found in preallocelemsandfreelist in kernel/bpf/stackmap.c in the bpf in the Linux kernel. In this flaw, the multiplication to calculate the size could lead to an integer overflow which could allow a local attacker, with a special user privilege, to gain...
