# CVE-2026-64224

> 3.1 LOW

## Beschreibung

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.
