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.
