Memory Management Vulnerability in OcteonTX2 Representor by Cavium

CVE-2026-64224

What is CVE-2026-64224?

A vulnerability exists within the Linux kernel affecting the OcteonTX2 representor, specifically in the rvu_rep_rsrc_init() function. This function allocates memory for queues before initializing hardware resources. If the hardware resource initialization fails, the system erroneously attempts to free the same resources again, leading to potential double free errors. The issue has been identified and traced back to an experimental tool focused on kernel memory management analysis. The improper cleanup sequence can create instability in systems utilizing OcteonTX2 hardware, necessitating prompt attention and resolution to maintain operational integrity.
