{"cve":"CVE-2026-64224","nvd":{"published":"2026-07-24T16:16:51.320","modified":"2026-08-12T00:11:26.863","status":"Analyzed","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nocteontx2-pf: fix double free in rvu_rep_rsrc_init()\n\nrvu_rep_rsrc_init() allocates queue memory before calling\notx2_init_hw_resources(). When hardware resource setup fails,\notx2_init_hw_resources() already unwinds the partially initialized\nSQ, CQ, and aura state before returning an error. The representor\nerror path then calls otx2_free_hw_resources() again and can free\nthe same resources a second time.\n\nFix this by splitting the cleanup labels so that a failure from\notx2_init_hw_resources() only releases queue memory. Keep the\notx2_free_hw_resources() call for failures that happen after\nhardware resource initialization completed successfully.\n\nThe bug was first flagged by an experimental analysis tool we are\ndeveloping for kernel memory-management bugs while analyzing\nv6.13-rc1. The tool is still under development and is not yet publicly\navailable. Manual inspection confirms that the bug is still\npresent in v7.1-rc3.\n\nRuntime validation was not performed because reproducing this path\nrequires OcteonTX2 representor hardware.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-415"],"references":["https://git.kernel.org/stable/c/8864b664d0443ecb8e56690e5546fcda5fe5e81b","https://git.kernel.org/stable/c/e8fb3de2a8effcaf62bec2c56b93d8bb480371d1","https://git.kernel.org/stable/c/eb72a65f2bb2cc059e2ca5d83de01fdf3ea602ad"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:46:40.600842820+00:00"},"epss":{"cve":"CVE-2026-64224","score":0.00128,"percentile":0.02402,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
