CVE-2026-64225
Description
In the Linux kernel, the following vulnerability has been resolved:
octeontx2-af: CGX: add bounds check to cgx_speed_mbps index
cgx_speed_mbps has 13 elements but RESP_LINKSTAT_SPEED can yield values 0-15. If it returns a value >= 13, this causes an out-of-bounds array access. Add a bounds check and default to speed 0 if the index is out of range.
