AI-suggested

Apply the official fix by updating the Linux kernel to a version that includes the specified commits resolving this issue. The vulnerability is fixed in the referenced commits, so upgrading to a patched kernel version is the recommended remediation.

Description

A vulnerability in the Linux kernel's octeontx2-af CGX component allowed out-of-bounds array access due to missing bounds checking on the cgx_speed_mbps index. The index could exceed the array size, leading to potential memory safety issues. This has been fixed by adding a bounds check that defaults to speed 0 if the index is out of range.
