{"id":"CVE-2026-64224","summary":"octeontx2-pf: fix double free in rvu_rep_rsrc_init()","details":"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.","modified":"2026-07-27T04:03:13.261217129Z","published":"2026-07-24T15:23:09.209Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64224.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/8864b664d0443ecb8e56690e5546fcda5fe5e81b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e8fb3de2a8effcaf62bec2c56b93d8bb480371d1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/eb72a65f2bb2cc059e2ca5d83de01fdf3ea602ad"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64224.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64224"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"3937b7308d4fce2793fa7fa56ed0faf0f8b6dc7a"},{"fixed":"8864b664d0443ecb8e56690e5546fcda5fe5e81b"},{"fixed":"eb72a65f2bb2cc059e2ca5d83de01fdf3ea602ad"},{"fixed":"e8fb3de2a8effcaf62bec2c56b93d8bb480371d1"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64224.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.34"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.11"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64224.json"}}],"schema_version":"1.7.5"}
