On failure, err_free_sq_ptrs only frees SQB\npages, leaving the per-SQ sqb_ptrs arrays behind.\n\nUse otx2_free_sq_res() for the SQ unwind path and let it free sqb_ptrs\neven when sq->sqe has not been allocated yet.\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 v7.1.1.\n\nAn x86_64 allyesconfig build showed no new warnings. As we do not have an\nOcteonTX2 PF device and the corresponding AF mailbox setup to test with,\nno runtime testing was able to be performed.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/148d7ec0a3a98839c320e6cdd112e2e88bfb091b","https://git.kernel.org/stable/c/23d917acd9c9a9fd999688ec3fdde7aa58ab8a14","https://git.kernel.org/stable/c/2cac2eac935ed7e0a9203204e036a1f6090ebc3d","https://git.kernel.org/stable/c/42c2836f10ac0427dac9e9a923d6ee2189dec544","https://git.kernel.org/stable/c/5df30f05db96552903680a17f858d250dfd9e86e"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72023","score":0.00216,"percentile":0.12136,"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).
