CVE-2026-64224

VendorlinuxProductlinux kernelDiscoveredJul 24, 2026UpdatedAug 12, 2026

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…
