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."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/net/ethernet/marvell/octeontx2/nic/rep.c"], "versions": [{"version": "3937b7308d4fce2793fa7fa56ed0faf0f8b6dc7a", "lessThan": "8864b664d0443ecb8e56690e5546fcda5fe5e81b", "status": "affected", "versionType": "git"}, {"version": "3937b7308d4fce2793fa7fa56ed0faf0f8b6dc7a", "lessThan": "eb72a65f2bb2cc059e2ca5d83de01fdf3ea602ad", "status": "affected", "versionType": "git"}, {"version": "3937b7308d4fce2793fa7fa56ed0faf0f8b6dc7a", "lessThan": "e8fb3de2a8effcaf62bec2c56b93d8bb480371d1", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/net/ethernet/marvell/octeontx2/nic/rep.c"], "versions": [{"version": "6.13", "status": "affected"}, {"version": "0", "lessThan": "6.13", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.34", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.0.11", "lessThanOrEqual": "7.0.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.13", "versionEndExcluding": "6.18.34"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.13", "versionEndExcluding": "7.0.11"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.13", "versionEndExcluding": "7.1"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/8864b664d0443ecb8e56690e5546fcda5fe5e81b"}, {"url": "https://git.kernel.org/stable/c/eb72a65f2bb2cc059e2ca5d83de01fdf3ea602ad"}, {"url": "https://git.kernel.org/stable/c/e8fb3de2a8effcaf62bec2c56b93d8bb480371d1"}], "title": "octeontx2-pf: fix double free in rvu_rep_rsrc_init()", "x_generator": {"engine": "bippy-1.2.0"}}}}
