Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
bpf: fix potential 32-bit overflow when accessing ARRAY map element<br />
<br />
If BPF array map is bigger than 4GB, element pointer calculation can<br />
overflow because both index and elem_size are u32. Fix this everywhere<br />
by forcing 64-bit multiplication. Extract this formula into separate<br />
small helper and use it consistently in various places.<br />
<br />
Speculative-preventing formula utilizing index_mask trick is left as is,<br />
but explicit u64 casts are added in both places.
