CVE-2026-74720

bpf: Preserve pointer state for commuted arithmetic

In the Linux kernel, the following vulnerability has been resolved:

bpf: Preserve pointer state for commuted arithmetic

When scalar += pointer is handled in adjust_ptr_min_max_vals(), the
destination register inherits the pointer state from the source pointer.
Copying only selected fields is fragile because pointer provenance is
tracked by several bpf_reg_state fields.

Use the caller's temporary offset register to preserve the scalar operand
while replacing the destination with the full pointer state. This preserves
the frame number for PTR_TO_STACK registers and keeps parent identity
fields consistent.
