If mlx5hws_matcher_resize_set_target() fails, the\nreplacement matcher is not attached anywhere and is leaked.\n\nFix the leak by destroying the replacement matcher before returning from\nthe resize-target failure path.\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 a\nmlx5 HWS-capable device to test with, no runtime testing was able to be\nperformed.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/1dce4f4bb3c1c02080b1a45bdd2abb2913a6642a","https://git.kernel.org/stable/c/a751ccdc6ea9bde154f25a5ba66926f462f96c19","https://git.kernel.org/stable/c/ae0265f0a95aaacef59d560a3e1ea36db8be9a52","https://git.kernel.org/stable/c/bb09d0e64ecaa0aa0f7d1133a1696ed74dead295"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72032","score":0.00206,"percentile":0.10586,"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).
