Description
In the Linux kernel, the following vulnerability has been resolved:
bpf: fix potential 32-bit overflow when accessing ARRAY map element
If BPF array map is bigger than 4GB, element pointer calculation can
overflow because both index and elem_size are u32. Fix this everywhere
by forcing 64-bit multiplication. Extract this formula into separate
small helper and use it consistently in various places.
Speculative-preventing formula utilizing index_mask trick is left as is,
but explicit u64 casts are added in both places.
Affected configurations
• linux linux kernel (>= 5.3 < 5.18.18)
• linux linux kernel (>= 5.19 < 5.19.2)
