CVE-2026-64225 Details
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.
A vulnerability in the Linux kernel's OcteonTX2 CGX driver allows for out-of-bounds array access. The issue arises because the 'cgx_speed_mbps' array, which has 13 elements, can be indexed by the 'RESP_LINKSTAT_SPEED' value that ranges from 0 to 15. If 'RESP_LINKSTAT_SPEED' returns a value of 13 or higher, it leads to an out-of-bounds access. This vulnerability affects the Linux kernel stable group.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been patched. The patch is included in the official Linux kernel repositories.
