[PATCH OLK-5.10] bpf: fix potential 32-bit overflow when accessing ARRAY map element
by Pu Lehui 01 Jul '25

01 Jul '25

From: Andrii Nakryiko <andrii(a)kernel.org> mainline inclusion from mainline-v6.0-rc1 commit 87ac0d600943994444e24382a87aa19acc4cd3d4 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICGA1J CVE: CVE-2022-50167 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- 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.
