CVE-2024-14040

CVE-2024-14040 affects the Linux kernel’s nexthop handling in ECMP/CLOS networks. The patch increases the nexthop weight width from 8-bit to 16-bit to accommodate large weight ratios (e.g., 1000:999) that don’t fit in 8 bits. The UAPI changes introduce a weight_high field and split fields to pres...
