CVE-2026-64224

In the Linux kernel, the following vulnerability has been resolved:

octeontx2-pf: fix double free in rvu_rep_rsrc_init()

rvu_rep_rsrc_init() allocates queue memory before calling

otx2_init_hw_resources(). When hardware resource setup fails,

otx2_init_hw_resources() already unwinds the partially initialized

SQ, CQ, and aura state before returning an error. The representor

error path then calls otx2_free_hw_resources() again and can free

the same resources a second time.

Fix this by splitting the cleanup labels so that a failure from

otx2_init_hw_resources() only releases queue memory. Keep the

otx2_free_hw_resources() call for failures that happen after

hardware resource initialization completed successfully.

The bug was first flagged by an experimental analysis tool we are

developing for kernel memory-management bugs while analyzing

v6.13-rc1. The tool is still under development and is not yet publicly

available. Manual inspection confirms that the bug is still

present in v7.1-rc3.

Runtime validation was not performed because reproducing this path

requires OcteonTX2 representor hardware.
